Choropleth map from Geopandas GeoDataFame

Question

I\'m trying to make a choropleth map from polygons in a Geopandas GeoDataFrame. I want to symbolize the polygons by quantiles of a value in one of the GeoDataFrame columns.

Answer 1

To adjust the polygon outline width, you can use "linewidth" like so:

tracts.plot(column='CRIME', scheme='QUANTILES', k=3, colormap='OrRd', linewidth=0.1)
