#Create a map

ontario_geo = "C:\\Users\\Almas\\Desktop\\torontomap.geojson"

map_toronto = folium.Map(location=[43.653963, -79.387207], zoom_start=10)

map_toronto.Choropleth(geo_data=ontario_geo,
    data = df,
    columns=['Postal Code','Average Price'],
    key_on='feature.properties.insee',
    fill_color='YlOrRd',
    fill_opacity=0.7, 
    line_opacity=0.2,
    legend_name='Toronto Home Values',).add_to(map_toronto) 

folium.LayerControl().add_to(map_toronto)
    
map_toronto

Answer 1

尝试：

    folium.Choropleth(geo_data=ontario_geo,
      data = df,
      columns=['Postal Code','Average Price'],
      key_on='feature.properties.insee',
      fill_color='YlOrRd',
      fill_opacity=0.7, 
      line_opacity=0.2,
      legend_name='Toronto Home Values',).add_to(map_toronto) 

Answer 2

我能够通过将“Average Price”列从object更改为integer来解决此问题。
