Choropleth Mapping with Folium

A Leaflet.js map created with Folium and a custom D3 threshold scale, with data bound between the Pandas DataFrame and the TopoJSON. See the Gist for the python code to generate the dataframe. The map was generated with the following Python code:

map_3 = folium.Map(location=[40, -99], zoom_start=4)
map_3.geo_json(geo_path=county_geo, data_out='data3.json', data=df,
               columns=['GEO_ID', 'Median_Household_Income_2011'],
               key_on='feature.id',
 fill_color='PuRd', line_opacity=0.3,

Folium and PySAL

This gist demonstrates the combined use of the Python Spatial Analysis Library PySAL together with Folium.
