Folium Choropleth + GeoJSON raises AttributeError: 'NoneType'

Question

I\'m trying to do a choropleth using folium which offers a great link between GeoJSON, Pandas and leaflet.

GeoJSON format is like below :

{
  \"type         


        

Answer 1

I had the same problem on JupyterLab (on labs.cognitiveclass.ai) using Folium 0.5.0. Then I copied my code and ran it in PyCharm, and it worked! I don't understand why, perhaps there is some backend issue (?)

If you want to display a folium map outside of a Jupyter notebook, you have to save the map to html:

map_france.save('map_france.html')

and open the html in your browser.
