Generating a density map using Python

In this section, we generate a (human) density map of the United States, where each state is color coded based on its relative population density.

How to do it...

We can use the script:

%matplotlib inline

import matplotlib.pyplot as plt
from mpl_toolkits.basemap import Basemap
from matplotlib.patches import Polygon
import pandas as pd
import numpy as np
import matplotlib

# create the map
map = Basemap(llcrnrlon=-119,llcrnrlat=22,urcrnrlon=-64,urcrnrlat=49,
 projection='lcc',lat_1=33,lat_2=45,lon_0=-95)# load the shapefile, use the name 'states'
# download from https://github.com/matplotlib/basemap/tree/master/examples/st99_d00.dbf,shx,shp
map.readshapefile('st99_d00&apos...
