usage of point_style for add_*() functions in leafmap module

[galaxismad]

Hi guys,
first of all great work with this library :-)

I was looking for a possibility to use circle markers with popups in an efficient way.
Using add_circle_makers_from_xy() gives me the expected result, although it seems to be not very efficient when using a high number of points (like over 3000 in this case, but I want to avoid to use marker clusters) as it is generating a

With pure ipyleaflet, this could be done using GeoJSON or GeoData plus defining point_style argument, which is super fast (see jupyter-widgets/ipyleaflet#439). Unfortunately, I didn't find a solution using point_style with leafmap. It seems, that functions using ipyleaflets GeoJSON under the hood are not making use of the point_style argument.

Is there a reason, why the point_style argument is not used/forwarded to the GeoJSON function (like add_gdf(), add_data() or add_geojson())? Maybe this system is not working together with creating the popups?

Thanks for your help in advance!

After some further testing, I found out, that it is possible to change the corresponding values directly for the layer before plotting the map like
layer.point_style = {'radius': 3}

As a site note: only with this, the default values given in hover style are applied and visible as well as info_mode = 'on_hover' shows the popup information as expected. Before, it was showing the toolbar box, but no content was shown, when hovering over the markers.

Hi @galaxismad,

I am facing the same issue where the point_style argument does not seem to be forwarded to the geosjon functions such as add_gdf(), add_data(), or add_geojson(). In your response, you mentioned using layer.point_style = {'radius': 3}, could you clarify how you used this? What type of object is layer in your example? Is it a geojson object, a geodataframe, or something else?
Did you import and use leafmap in the standard way?

I would appreciate any insights, as I have not found a solution to apply specific styles to my points yet.

Thanks in advance!

@galaxismad Thank you for the suggestion. point_style support has been added in #1043
