You can create a treemap with colors mapped on values by using squarify and matplotlib libraries. In the following example, in order to map colors, matplotlib.colors.Normalize() is used with vmin and vmax, minimum values and maximum values respectively. Each value in my_values list is normalized and then map to a color.

import matplotlib
import matplotlib.pyplot as plt
import squarify # pip install squarify (algorithm for treemap)</pre>
# Create a dataset:
my_values=[i**3 for i in range(1,100)]
# create a color palette, mapped to these values
cmap =
norm = matplotlib.colors.Normalize(vmin=mini, vmax=maxi)
colors = [cmap(norm(value)) for value in my_values]
# Change color
squarify.plot(sizes=my_values, alpha=.8, color=colors )
