Error in chloropleth function

[jnclelland]

When trying to use the chloropleth function as in the docs, I get the following error:

"AttributeError: module 'matplotlib.cm' has no attribute 'get_cmap'"

A google search reveals that as of Matplotlib 3.9, the command

"colorbarmap = plt.cm.get_cmap(cmap, len(boundaries))"

on line 89 of chloropleth.py is no longer valid syntax and should be replaced by

"colorbarmap = plt.get_cmap(cmap, len(boundaries))"

Making this change fixed the problem for me.
