Plotly Express lines on maps

Today, px.line_mapbox and px.line_geo expect rows which are points, which are then split into groups and connected by lines.

In most GIS formats, however, as wrapped by GeoPandas, the entire line feature is often stored in a single row, just like choropleth geometries. We should have either a new pair of PX functions for this (px.line_feature_mapbox?) or an option to the existing functions (px.line_mapbox(geojson=<geojson>)) to support this option out of the box.

Just wanted to give this a bump!

Out-of-the-box support for shapely/GeoPandas LineStrings would be fantastic. I’m aware you’ve added some support for Shapely Points and Polygons. The GeoPandas support example given in Lines on Maps is useful but it doesn’t really exploit the strengths of pandas, as it involves unpacking the dataframe using a loop.

Thanks for all the work so far though! 🙂

This will be a game changing enhancement since it will make plotly a viable alternative for representing geospatial data instead of GIS software. In addition I would like to suggest the following: People working with geospatial data are very used to be able to control the width, apart form the color of the line. I suppose this can be achieved already by iterating over each line and adjusting its width. However, straightforwardly providing this capability in px would be very useful. Cheers
