Use webgl powered layers

[martinRenou]

It can be slow to have lots of markers and polygons. Using a WebGL powered layer could be nice, there is this extension: https://github.com/manubb/Leaflet.PixiOverlay which allows putting millions of markers on the Map, and using huge GeoJSON files. It might be a nice addition to ipyleaflet, and we could shamelessly reuse their examples.

Hi Martin. Is there any update on this feature? I am using ipyleaflet and working with a dataset with about 15000 markers (Lat/Longs). I am using ipywidgets dropdown to filter the number of markers to be shown on the map based on the county selected. I am experiencing slow performance in terms of the markers being rendered on the map. Also, I am using the markercluster feature. I feel like this enhancement mentioned above might work pretty well for me. Do you have any suggestions?

Hey! If you want to add this feature in ipyleaflet I could help you through the process :) I don't really have much time to do it myself but I am happy to help.

I don't have much experience with programming. I was amazed by how easy it was to build a GIS application in ipyleaflet. I am dealing with large datasets from the electric grid and am experiencing slow rendering of markerclusters on the map.
