features.GeoJson Tooltip

See original GitHub issue

Noticing in the latest documentation that there is now a tooltip option in the folium.features.GeoJson class.

Right now it looks like it only takes raw strings - would it be possible to borrow some syntax from style_function and highlight_function in this class to a function call back to the GeoJson via a tooltip = lambda feature: feature['properties'][value] structure, or to possibly wrap this into the highlight_function mouseover event dictionary to assist in the user’s exploration of the data (similar to this D3 visual). A popup in this vein would be really functional as well, particularly when paired with some of the Vega/Vega-Lite offerings.

I’m new to JS, but going through the leaflet tutorials right now. I’ve never made a PR before, but really enjoy this library and would love to contribute if someone could steer me in the right direction to start.

Thank you!

This is now referenced in PR #883. Added new Tooltip Class object to enable for flexible data handling across different data structures. I’m not super familiar with the Topojson standard and how folium/Leaflet works with it but the specs in that folium class look pretty similar to GeoJson so I think this could be handled in that Jinja2 template as well.

Tooltips for GeoJson have been added in #883 so I’m closing this issue.
