Welcome to the Python Outbreak.info package docs!

+

Here you can find information on the functions you will use to collect and analyze SARS-COV-2 data from the Outbreak.info API. +Our package pulls data from the Outbreak.info API and is reflected on our Outbreak.info web interface

+
+

Installation

+

We recommend installing the package via pip using:

+

pip install python-outbreak-info

+

Alternatively, the package can be directly installed from source via pip:

+

pip install git+https://github.com/outbreak-info/python-outbreak-info.git

+
+
+

Getting Started

+

The Python Outbreak.info package contains key functions for accessing genomic and epidemiological data for SARS-CoV-2. Access to genomic data requires logging in using GISAID credentials to generate an API key, using the authenticate_new_user() function. To perform authentication, you’ll need to first run

+
from outbreak_data import authenticate_user
+authenticate_user.authenticate_new_user()
+
+
+

and then you should be able access all of the functionality of the package. Most of the rest of the tools are available within the outbreak_data component of the package. For example:

+
from outbreak_data import outbreak_data
+lin_list = ['B.1.1.7','B.1.351','B.1.617.2']
+# request lineages occurring with minimum frequency of 0.05 (5%)
+df = outbreak_data.lineage_mutations(lin_list,freq=0.05)
+# filter mutations and sort by codon number
+df = df[df['gene']=='S'].sort_values(by='codon_num')
+
+
+

For location-specific analyses, users will need to supply the appropriate location code corresponding to their location of interest. To do this, we provide an ID lookup tool kit via the outbreak_tools part of the package. An example lookup should look like:

+
from outbreak_tools import outbreak_tools
+location_list = outbreak_tools.id_lookup(['Illinois','South Africa','Chile'])
+# which returns ['USA_US-IL', 'ZAF', 'CHL']
+
+
+
+

Note

+

This project is under active development.

cases_by_location(location)

+
+
+outbreak_data.cases_by_location(location, server='api.outbreak.info', auth=None, pull_smoothed=0)
+

Loads data from a location if input is a string, or from multiple locations +if location is a list of string locations. Since this API endpoint supports paging, collect_all is used to return all data.

+
+
Arguments:
+
location
+

A string or list of strings, separate multiple locations by “,”

+
+
pull_smoothed
+

For every value >= 0, returns 1000 obs. (paging)

param location_id
+

(Optional). A string; If not specified, return most recent date globally.

+
+
param pangolin_lineage
+

(Optional). If not specfied, returns all Pango lineages containing that mutation.

+
+
param frequency
+

(Optional) Minimimum frequency threshold for the prevalence of a mutation in a lineage.

Tracing Mutations Back to Lineage

+

The Python Outbreak API can be queried in order to determine which lineages a mutation has been found in. After collecting a sample and determining what sequences are present, we may have a list of several SARS-CoV-2 mutations that we can immediately say are characteristic of a specific variant. However in some cases, we also may have a mutation that is relatively uncommon in most other samples. +For example, we can look at small data sample consisting of 10 mutations: (S:A67V, S:DEL69/70, S:E484A, S:N501Y, S:T572N, S:D614G, S:G142D N:S2Y, S:Q52R, E:L21F, S:G593D). We’ll want a way to find more details about any mutation collected, such as whether the mutation has been collected before, when, and where that mutation came from.

+

To start, the mutations_by_lineage() function allows us to look at the clinical prevalence of a mutation and see which lineage it most likely belongs to. Let’s try it for E:L21F:

+
# Perform authentication if you haven't already
+from outbreak_data import authenticate_user
+authenticate_user.authenticate_new_user()
+
+# Import outbreak_data package
+from outbreak_data import outbreak_data as od
+
+lin1 = od.mutations_by_lineage(mutation='E:L21F')
+print(lin1)
+
+
+
+

This mutation has clearly been seen before in some previous lineages. We might be able recognize that most of the mutations in our list have been detected in older variants, as well as Omicron. However, S:G593D is relatively uncommon in most other samples. We can easily find out where and when it was last detected:

+
>>>  lin2 = od.mutations_by_lineage(mutation='S:G593D')
+>>>  print(lin2)
+
+     pangolin_lineage  lineage_count  mutation_count  proportion  \
+ 0            xbb.1          28205               1    0.000035
+
+    proportion_ci_lower  proportion_ci_upper
+ 0             0.000004             0.000166
+
+
+>>>  last_seen = od.collection_date('xbb.1', 'S:G593D')
+>>>  print(last_seen)
+
+                Values
+ date        2022-12-12
+ date_count           1
+
+
+

According to our data, S:G593D has only been detected once in a single sequence belonging to the xbb.1 lineage. The last time it was collected was back on December 12, 2022.

+

Additionally mutations_by_lineage allows us to find out if there is a lineage where several mutations overlap. Selecting 7 of the mutations from our original list yields one lineage with all of these mutation characteristics:

+
>>> lin3 = od.mutations_by_lineage(mutation='S:A67V, S:DEL69/70, S:E484A, S:N501Y, S:T572N, S:D614G, S:G142D')
+>>> print(lin3)
+
+     pangolin_lineage  lineage_count  mutation_count  proportion  \
+   0          ba.1.19           4587               1    0.000218
+
+   proportion_ci_lower  proportion_ci_upper
+0             0.000024             0.001019
+
+
+

Here we see that the only lineage that contains all 7 mutations is ba.1.19.

Working with epidemiological data

+

The outbreak_data package contains endpoints that return epidemiological data on SARS-CoV-2. We can then visualize how SARS-CoV-2 is affecting countries around the world (with the help of one of the many plotting packages available for Python).

+

For example, we can look at the pattern of infection counts in California during a specific point in time:

+
# Perform authentication
+from outbreak_data import authenticate_user
+authenticate_user.authenticate_new_user()
+
+# Import outbreak_data package
+from outbreak_data import outbreak_data as od
+import pandas as pd
+
+# Get the number of increased cases from the previous day in California
+counts_ca = od.cases_by_location('USA_US-CA')
+# Formatting for graph
+counts_ca= counts_ca.rename(columns={"admin1": "location"})
+# Sort info by date and search within a date range
+counts_ca = counts_ca.sort_values(by = "date")
+counts_ca = counts_ca.loc[counts_ca["date"].between("2021-05-15", "2021-08-15")]
+print(counts_ca)
+
+#Import visual package of choice
+import altair as alt
+
+#Graph!
+alt.Chart(xbb_mutations, title = "Daily ORF1a:K47R AND S:T19I Prevalence of Lineage XBB").mark_line().encode(
+x='date:T',
+y=alt.Y('proportion (%):Q'),
+color = 'mutations:N')

Genomic Analysis

+

The outbreak_data package has contains multiple tools that can collect the relevant genomic information on SARS-CoV-2. Using a combination of these endpoints will allow you to get the information on variants of concern (VoC) and the current mutations to conduct your own multi-level genomic analysis on SARS-CoV-2. On this page, you’ll find a few example workflows that demonstrate data manipulation and visualization steps to track the progression of SARS-CoV-2.

+

Here is an example workflow that allows the user to manipulate the data to find all the XBB lineages prevalent in India within a 1-year timeframe:

+
# Perform authentication if you haven't already
+from outbreak_data import authenticate_user
+authenticate_user.authenticate_new_user()
+
+# Import outbreak_data package
+from outbreak_data import outbreak_data as od
+
+# Get the prevalence of all circulating XBB lineages in India
+data = od.prevalence_by_location("IND", startswith = 'xbb')
+# multiply prevalence values by 100% for scale
+data['prevalence_rolling'] = data['prevalence_rolling'].apply(lambda x: x*100)
+# Search for data based on date range
+data = data.sort_values(by="date")
+data = data.loc[data["date"].between("2020-09-12", "2022-03-31")]
+
+## Use the visual package of your choice to create an area graph using your data
+import altair as alt
+
+# Graph of results
+alt.Chart(data, title = "Lineage Prevalence in India").mark_area().encode(
+x='date:T',
+y=alt.Y('prevalence_rolling:Q'),
+color = 'lineage:N')
+

Lineage_Mutations Heatmap

+

A basic but important question: how do we define a lineage? What mutations consistently appear in most sequences within a lineage? We could start by plotting some of the characteristic mutations of XBB occurring in 80% of sequences. Even better, we can do this for mulitple related lineages and compare them using a heatmap:

+
# Collecting 15 characteristic mutations and their prevalences for each variant
+lin0 = od.lineage_mutations("xbb", freq = 0.80)
+lin0["lineage"] = "xbb"
+lin0 = lin0.iloc[:15]
+
+lin1 = od.lineage_mutations("xbb.1", freq = 0.80)
+lin1["lineage"] = "xbb.1"
+lin1 = lin1.iloc[:15]
+
+lin2 = od.lineage_mutations("xbb.1.5", freq = 0.80)
+lin2["lineage"] = "xbb.1.5"
+lin2 = lin2.iloc[:15]
+
+lin3 = od.lineage_mutations("xbb.1.16", freq = 0.80)
+lin3["lineage"] = "xbb.1.16"
+lin3 = lin3.iloc[:15]
+
+lin4 = od.lineage_mutations("xbb.1.9", freq = 0.80)
+lin4["lineage"] = "xbb.1.9"
+lin4 = lin4.iloc[:15]
+
+lin5 = od.lineage_mutations("xbb.2.3", freq = 0.80)
+lin5["lineage"] = "xbb.2.3"
+lin5 = lin5.iloc[:15]
+
+# Link each of the findings together for plotting
+df = pd.concat([lin0, lin1, lin2, lin3, lin4, lin5])
+df["prevalence"] = df["prevalence"].apply(lambda x: x*100)
+df= df.rename(columns={'prevalence': 'prevalence %'})
+
+# Plot mutation heatmap
+import altair as alt
+
+alt.Chart(df).mark_rect().encode(

Comparing Lineages

+

To better understand the evolution of SARS-CoV-2, we may also want to know what mutations are shared between different viral lineages and how many shared mutations there are.

+

For this example we’ll look at three different lineages: B.1.1.7, P.1, and B.1.1.529. First, let’s get an idea of which mutations are shared between all three lineages:

+
lin1 = od.lineage_mutations("b.1.1.7")
+lin1["lineage"] = "b.1.1.7"
+
+lin2 = od.lineage_mutations("P.1")
+lin2["lineage"] = "P.1"
+
+lin3 = od.lineage_mutations("b.1.1.529")
+lin3["lineage"] = "b.1.1.529"
+
+#Finding intersections
+
+#Created an optional but convenient intersecting function
+def intersect(lst1, lst2):
+    return set(lst1).intersection(lst2)
+
+a = set(lin1['mutation'])
+b = set(lin2['mutation'])
+c = set(lin3['mutation'])
+
+m12 = intersect(a, b)
+m13 = intersect(a, c)
+m23 = intersect(b, c)
+m123 = intersect(m12, c)
+
+print('Set 1.2:', m12)
+print('Set 1.3:', m13)
+print('Set 2.3:' , m23)
+print('Set 1.2.3:', m123)
+
+
+
+
Output
+
 Set 1.2: {'orf1b:p314l', 'orf8:s84l', 'orf1a:del3675/3677', 'n:r203k', 's:d614g', 's:n501y', 'n:g204r'}
+ Set 1.3: {'s:p681h', 'orf1b:p314l', 'orf8:s84l', 'n:r203k', 's:d614g', 'n:g204r'}
+ Set 2.3: {'orf1b:p314l', 's:h655y', 'orf8:s84l', 'n:r203k', 's:d614g', 'n:g204r'}
+ Set 1.2.3: {'orf1b:p314l', 'orf8:s84l', 'n:r203k', 's:d614g', 'n:g204r'}
+
+
+
+

Finally, we can make a visual based on our findings and create a Venn diagram of our results:

+
# Import libraries for venn diagram visual
+from matplotlib_venn import venn3, venn3_circles
+from matplotlib import pyplot as plt
+
+# Using matplotlib_venn to make venn diagram with custom visuals
+ ## The venn diagram package used here automatically determines the number
+ ## of intersecting values and plots accordingly
+
+vd3 = venn3([a, b, c], set_labels = ('Alpha/B.1.1.7', 'Gamma/P.1', 'Omicron/B.1.1.529'), set_colors=('#c4e6ff', '#F4ACB7','#9D8189'),
+ alpha = 0.8)
+c = venn3_circles([a, b, c,], linestyle = '-.', linewidth=2, color='grey')
+for text in vd3.set_labels:
+ text.set_fontsize(16);
+for text in vd3.subset_labels:
+ text.set_fontsize(16)
+plt.title('Number of Overlapping Mutations in 3 Variants',fontname ='Helvetica',fontweight ='bold',fontsize = 18,
+ pad = 30,backgroundcolor ='#cbe7e3',color ='black', style ='normal');
+c[0].set_lw(7.0)
+c[0].set_ls(':')
+plt.show()
+
+
+_images/compare.png +

We can see that the graph matches the number of intersecting mutations that we previously saw, given that the venn diagram also takes into account unique values for each set.

+
+

Note

+

Please see the matplotlib venn diagram documentation and this article for more info on how to create these graphs.

+
+

Finding the Most Prevalent Lineages

+

If we wanted to determine and plot the top four most prevalent lineages in India, we can make a few queries and use a few simple commands to create a table that shows us what these lineages are:

+
data=od.prevalence_by_location("IND")
+most_prev = data.groupby('lineage').apply(max) # Finds the lineages with the most hits
+most_prev = most_prev.mask(most_prev == '').dropna(how = 'any') # Drop any unknowns
+most_prev = most_prev.iloc[:4]
+print(most_prev)
+
+
+
+
Output
+
                  date  total_count  lineage_count    lineage  prevalence  \
+ lineage
+ ba.2       2023-04-20         5668           1445       ba.2    0.822785
+ ba.2.10.1  2023-04-19         5668             93  ba.2.10.1    0.285714
+ bq.1.1     2023-03-27          402              7     bq.1.1    0.428571
+ ch.1.1     2023-02-13          119              4     ch.1.1    0.400000
+
+            prevalence_rolling
+ lineage
+ ba.2                 0.677541
+ ba.2.10.1            0.095541
+ bq.1.1               0.156863
+ ch.1.1               0.066667
+
+
+
+

Next we’ll collect the prevalence data on each of the four lineages:

+
# Retrieve the official data on the prevalences of these lineages using `daily_prev()`
+d1 = od.daily_prev('ba.2', "IND")
+d2 = od.daily_prev('ba.2.10.1', "IND")
+d3 = od.daily_prev('bq.1.1', "IND")
+d4 = od.daily_prev( 'ch.1.1', "IND")
+
+# Formatting for creating the graph
+d1['lineage'] = 'ba.2'
+d2['lineage'] = 'ba.2.10.1'
+d3['lineage'] = 'bq.1.1'
+d4['lineage'] = 'ch.1.1'
+
+# Group together data from each lineage
+data = pd.concat([d1, d2, d3, d4])
+data = data.rename(columns = {'proportion': 'proportion (%)'})
+
+#Pick a date range to analyze
+data = data.sort_values(by="date")
+data = data.loc[data["date"].between("2022-09-12", "2023-03-31")]
+# Increase prevalence by 100%
+data['proportion'] = data['proportion'].apply(lambda x: x*100)
+
+#Graph using preferred visual package
+import altair as alt
+alt.Chart(data, title = "Top 4 Most Prevalent Lineages in India").mark_area().encode(
+x='date:T',
+y=alt.Y('proportion (%):Q'),
+color = 'lineage:N')

Welcome to the Python Outbreak.info package docs!

+

Here you can find information on the functions you will use to collect and analyze SARS-COV-2 data from the Outbreak.info API. +Our package pulls data from the Outbreak.info API and is reflected on our Outbreak.info web interface

+
+

Installation

+

We recommend installing the package via pip using:

+

pip install python-outbreak-info

+

Alternatively, the package can be directly installed from source via pip:

+

pip install git+https://github.com/outbreak-info/python-outbreak-info.git

+
+
+

Getting Started

+

The Python Outbreak.info package contains key functions for accessing genomic and epidemiological data for SARS-CoV-2. Access to genomic data requires logging in using GISAID credentials to generate an API key, using the authenticate_new_user() function. To perform authentication, you’ll need to first run

+
from outbreak_data import authenticate_user
+authenticate_user.authenticate_new_user()
+
+
+

and then you should be able access all of the functionality of the package. Most of the rest of the tools are available within the outbreak_data component of the package. For example:

+
from outbreak_data import outbreak_data
+lin_list = ['B.1.1.7','B.1.351','B.1.617.2']
+# request lineages occurring with minimum frequency of 0.05 (5%)
+df = outbreak_data.lineage_mutations(lin_list,freq=0.05)
+# filter mutations and sort by codon number
+df = df[df['gene']=='S'].sort_values(by='codon_num')
+
+
+

For location-specific analyses, users will need to supply the appropriate location code corresponding to their location of interest. To do this, we provide an ID lookup tool kit via the outbreak_tools part of the package. An example lookup should look like:

+
from outbreak_tools import outbreak_tools
+location_list = outbreak_tools.id_lookup(['Illinois','South Africa','Chile'])
+# which returns ['USA_US-IL', 'ZAF', 'CHL']
+
+
+
+

Note

+

This project is under active development.

Lineage Prevalence Analysis

+

The outbreak_data package has contains multiple endpoints that can collect information on SARS-CoV-2 lineages. Pulling data from a combination of endpoints will allow you to conduct your own analysis on the progression of SARS-CoV-2. On this page, you’ll find a few example workflows that demonstrate how to collect, manipulate, and visualize prevalence data in SARS-CoV-2 lineages.

+

Here is how we would go about collecting data to find all the XBB lineages prevalent in India within a 1-year timeframe:

+
# Perform authentication if you haven't already
+from outbreak_data import authenticate_user
+authenticate_user.authenticate_new_user()
+
+# Import outbreak_data package
+from outbreak_data import outbreak_data as od
+
+# Get the prevalence of all circulating XBB lineages in India
+data = od.prevalence_by_location("IND", startswith = 'xbb')
+# multiply prevalence values by 100% for scale
+data['prevalence_rolling'] = data['prevalence_rolling'].apply(lambda x: x*100)
+# Search for data based on date range
+data = data.sort_values(by="date")
+data = data.loc[data["date"].between("2020-09-12", "2022-03-31")]
+
+## Use the visual package of your choice to create an area graph using your data
+import altair as alt
+
+# Graph of results
+alt.Chart(data, title = "Lineage Prevalence in India").mark_area().encode(
+x='date:T',
+y=alt.Y('prevalence_rolling:Q'),
+color = 'lineage:N')
+
+
+

Finding the Most Prevalent Lineages

+

If we wanted to determine and plot the top four most prevalent lineages in India, we can make a few queries and use a few simple commands to create a table that shows us what these lineages are:

+
data=od.prevalence_by_location("IND")
+most_prev = data.groupby('lineage').apply(max) # Finds the lineages with the most hits
+most_prev = most_prev.mask(most_prev == '').dropna(how = 'any') # Drop any unknowns
+most_prev = most_prev.iloc[:4]
+print(most_prev)
+
+
+
+
Output
+
                  date  total_count  lineage_count    lineage  prevalence  \
+ lineage
+ ba.2       2023-04-20         5668           1445       ba.2    0.822785
+ ba.2.10.1  2023-04-19         5668             93  ba.2.10.1    0.285714
+ bq.1.1     2023-03-27          402              7     bq.1.1    0.428571
+ ch.1.1     2023-02-13          119              4     ch.1.1    0.400000
+
+            prevalence_rolling
+ lineage
+ ba.2                 0.677541
+ ba.2.10.1            0.095541
+ bq.1.1               0.156863
+ ch.1.1               0.066667
+
+
+
+

Next we’ll collect the prevalence data on each of the four lineages:

+
# Retrieve the official data on the prevalences of these lineages using `daily_prev()`
+d1 = od.daily_prev('ba.2', "IND")
+d2 = od.daily_prev('ba.2.10.1', "IND")
+d3 = od.daily_prev('bq.1.1', "IND")
+d4 = od.daily_prev( 'ch.1.1', "IND")
+

Viral Mutation Analysis

+

Lineage_Mutations Heatmap

+

A basic but important question: how do we define a lineage? What mutations consistently appear in most sequences within a lineage? We could start by plotting some of the characteristic mutations of XBB occurring in 80% of sequences. Even better, we can do this for mulitple related lineages and compare them using a heatmap:

+
# Perform authentication if you haven't already
+from outbreak_data import authenticate_user
+authenticate_user.authenticate_new_user()
+
+# Import outbreak_data package
+from outbreak_data import outbreak_data as od
+
+
+# Collecting 15 characteristic mutations and their prevalences for each variant
+
+lin0 = od.lineage_mutations("xbb", freq = 0.80)
+lin0["lineage"] = "xbb"
+lin0 = lin0.iloc[:15]
+
+lin1 = od.lineage_mutations("xbb.1", freq = 0.80)
+lin1["lineage"] = "xbb.1"
+lin1 = lin1.iloc[:15]
+
+lin2 = od.lineage_mutations("xbb.1.5", freq = 0.80)
+lin2["lineage"] = "xbb.1.5"
+lin2 = lin2.iloc[:15]
+

+
+lin4 = od.lineage_mutations("xbb.1.9", freq = 0.80)
+lin4["lineage"] = "xbb.1.9"
+lin4 = lin4.iloc[:15]
+
+lin5 = od.lineage_mutations("xbb.2.3", freq = 0.80)
+lin5["lineage"] = "xbb.2.3"
+lin5 = lin5.iloc[:15]
+
+# Link each of the findings together for plotting
+df = pd.concat([lin0, lin1, lin2, lin3, lin4, lin5])
+df["prevalence"] = df["prevalence"].apply(lambda x: x*100)
+df= df.rename(columns={'prevalence': 'prevalence %'})
+
+# Plot mutation heatmap
+import altair as alt

Comparing Lineages

+

To better understand the evolution of SARS-CoV-2, we may also want to know what mutations are shared between different viral lineages and how many shared mutations there are.

+

For this example we’ll look at three different lineages: B.1.1.7, P.1, and B.1.1.529. First, let’s get an idea of which mutations are shared between all three lineages:

+
lin1 = od.lineage_mutations("b.1.1.7")
+lin1["lineage"] = "b.1.1.7"
+
+lin2 = od.lineage_mutations("P.1")
+lin2["lineage"] = "P.1"
+
+lin3 = od.lineage_mutations("b.1.1.529")
+lin3["lineage"] = "b.1.1.529"
+
+#Finding intersections
+
+#Created an optional but convenient intersecting function
+def intersect(lst1, lst2):
+    return set(lst1).intersection(lst2)
+
+a = set(lin1['mutation'])
+b = set(lin2['mutation'])
+c = set(lin3['mutation'])
+
+m12 = intersect(a, b)
+m13 = intersect(a, c)
+m23 = intersect(b, c)
+m123 = intersect(m12, c)
+
+print('Set 1.2:', m12)
+print('Set 1.3:', m13)
+print('Set 2.3:' , m23)
+print('Set 1.2.3:', m123)
+
+
+
+
Output
+
 Set 1.2: {'orf1b:p314l', 'orf8:s84l', 'orf1a:del3675/3677', 'n:r203k', 's:d614g', 's:n501y', 'n:g204r'}
+ Set 1.3: {'s:p681h', 'orf1b:p314l', 'orf8:s84l', 'n:r203k', 's:d614g', 'n:g204r'}
+ Set 2.3: {'orf1b:p314l', 's:h655y', 'orf8:s84l', 'n:r203k', 's:d614g', 'n:g204r'}
+ Set 1.2.3: {'orf1b:p314l', 'orf8:s84l', 'n:r203k', 's:d614g', 'n:g204r'}
+
+
+
+

Finally, we can make a visual based on our findings and create a Venn diagram of our results:

+
# Import libraries for venn diagram visual
+from matplotlib_venn import venn3, venn3_circles
+from matplotlib import pyplot as plt
+
+# Using matplotlib_venn to make venn diagram with custom visuals
+ ## The venn diagram package used here automatically determines the number
+ ## of intersecting values and plots accordingly
+
+vd3 = venn3([a, b, c], set_labels = ('Alpha/B.1.1.7', 'Gamma/P.1', 'Omicron/B.1.1.529'), set_colors=('#c4e6ff', '#F4ACB7','#9D8189'),
+ alpha = 0.8)
+c = venn3_circles([a, b, c,], linestyle = '-.', linewidth=2, color='grey')
+for text in vd3.set_labels:
+ text.set_fontsize(16);
+for text in vd3.subset_labels:
+ text.set_fontsize(16)
+plt.title('Number of Overlapping Mutations in 3 Variants',fontname ='Helvetica',fontweight ='bold',fontsize = 18,
+ pad = 30,backgroundcolor ='#cbe7e3',color ='black', style ='normal');
+c[0].set_lw(7.0)
+c[0].set_ls(':')
+plt.show()
+
+
+_images/compare.png +

We can see that the graph matches the number of intersecting mutations that we previously saw, given that the venn diagram also takes into account unique values for each set.

+
+

Note

+

Please see the matplotlib venn diagram documentation and this article for more info on how to create these graphs.
