Generation of diagrams and flowcharts from text in a similar manner as markdown.

+ +

Ever wanted to simplify documentation and avoid heavy tools like Visio when explaining your code?

+ +

This is why mermaid was born, a simple markdown-like script language for generating charts from text via javascript.

+ +

+ Syntax

+ +

+ Graph

+ +

This statement declares a new graph and the direction of the graph layout.

+ + 
graph TD
+
+ +

This declares a graph oriented from top to bottom.

+ +

Example 3

+ + 
graph LR
+
+ +

This declares a graph oriented from left to right.

+ +

Possible directions are:

+ +
    +
  • TB - top bottom
    • +
  • BT - bottom top
    • +
  • RL - right left

Example 4

+ +

+ Nodes

+ +

+ A node (default)

+ + 
id1;
+
+ +

Single node

+ +

Note that the id is what is displayed in the box.

+ +

+ A node with text

+ +

It is also possible to set text in the box that differs from the id. If this is done several times, it is the last text + found for the node that will be used. Also if you define edges for the node later on, you can omit text definitions. The + one previously defined will be used when rendering the box.

+ + 
id1[This is the text in the box];
+
+ +

Text in node

+ +

+ A node with round edges

+ + 
id1(This is the text in the box);
+
+ +

Node with round edges

+ +

+ A node in the form of a circle

+ + 
id1((This is the text in the box));
+
+ + + +

+ A node in an asymetric shape

+ + 
id1>This is the text in the box];
+
+ + + +

+ A node (rhombus)

+ + 
id1{This is the text in the box};
+
+ + + +

+ Styling a node

+ +

It is possible to apply specific styles such as a thicker border or a different background color to a node.

+ + 
graph LR;
+                id1(Start)-->id2(Stop);
+                style id1 fill:#f9f,stroke:#333,stroke-width:4px;
+                style id2 fill:#ccf,stroke:#f66,stroke-width:2px,stroke-dasharray: 5, 5;
+
+ + +

+ Classes

+ +

More convenient then defining the style everytime is to define a class of styles and attach this class to the nodes that + should have a different look.

+ +

a class definition looks like the example below:

+ + 
    classDef className fill:#f9f,stroke:#333,stroke-width:4px;
+
+ +

Attachment of a class to a node is done as per below:

+ + 
    class nodeId1 className;
+
+ +

It is also possible to attach a class to a list of nodes in one statement:

+ + 
    class nodeId1,nodeId2 className;
+
+ +

+ Default class

+ +

If a class is named default it will be assigned to all classes without specific class definitions.

+ + 
    classDef default fill:#f9f,stroke:#333,stroke-width:4px;
+
+ +

+ Links between nodes

+ +

Nodes can be connected with links/edges. It is possible to have different types of links or attach a text string to a link.

+ +

+ A link with arrow head

+ + 
A-->B;
+
+ +

Link with arrowhead

+ +

+ An open link

+ + 
A---B;
+
+ +

Open link

+ +

+ Text on links

+ + 
A---|This is the text|B;
+
+ +

Text on links

+ +

+ Styling links

+ +

It is possible to style links for instance a link that is going back in the flow. This is done by the linkStyle statement as in the example below:

+ + 
linkStyle 3 stroke:#ff3,stroke-width:4px;
+
+ +

+ Interaction

+ +

It is possible to bind a click event to a node:

+ + 
click nodeId callback
+
+ +
    +
  • nodeId is the id of the node
    • +
  • callback is the name of a javascript function defined on the page displaying the graph, the function will be called with the nodeId as parameter.
