Dynamization in Folium

[Theagainmen]

Describe the solution you'd like
I would like to update marker data live based on actual data. Same goes for the data in the marker pop-up. I would also like to draw circles and maybe add or remove markers based on live data.

Describe alternatives you've considered
Writing in JavaScript with Leaflet.js itself, but my JavaScript is not good.

Additional context
Maybe there is already another Python package that supports this, but I do not think so, if there is I would appreciate if anyone could let me know!

Implementation
I am not sure how this could be implemented, since my Python and JavaScript knowledge is limited.

Thanks for developing Folium, makes it a lot easier to use for non JavaScript people!

I would also like this to be added! :)

Check out https://github.com/jupyter-widgets/ipyleaflet which is much more dynamic than folium.

There's also this discussion: #848

And this one: #906

Hope it helps!

Is this usable outside of Jupyter notebook?

ipyleaflet is specifically for in Notebooks

Okay - I am developing an application that is not using a Jupyter Notebook - thank you for the suggestion anyway!

Well, I am doing the same. But facing same issues, @pstatonwx any luck?

Nope :( It looks like we're out of luck on this front.

Sorry to hear that. Any alternate ways adopted?.
I am trying to move the maker on map without re-rendering/refreshing of map in Python application, (developed in Qt6). I have used folium but the problem is that each time tha map has to be rendered, when the marker moves, and then has to be plotted/viewed in HTML. That causes the flashing of screen. I am wondering how this would be done in softweares like mission planner, goolge and careem etc?

Thank you @pstatonwx for your repsone.

Unfortunately that is what I have found as well, there's no way to dynamically add/remove content with Python/Folium. The only other way would be to use JavaScript to make an actual Leaflet map.

@pstatonwx thanky very much for your time and concern!

If you are looking for a Python solution outside Jupyter notebook, Streamlit pydeck chart kind of allows adding and removing layers without refreshing the entire map.

Thanks! I can't completely speak for @MuhammadQaisarAli , but at least for me, I'm only adding/removing polygons on a map, not entire layers. Is this something that Streamlit pydeck chart could achieve?

For instance, mine is a weather application displaying warnings - if a tornado warning is issued, I need the polygon for the affected area to pop up on my Folium map, and then when it expires, it needs to disappear. In the current framework, this requires a full page refresh.

[giswqs]

Yes, I believe so. I did that before using streamlit pydeck chart. It can add/remove layers dynamically without refreshing the entire map, kind of like ipyleaflet for Jupyter notebook.

Thank you Professor @giswqs . I will have a try to this.
