Most heatmap tutorials I found online use pyplot.pcolormesh with random sets of
data from Numpy; I just needed to plot x, y, z values stored in lists--without
all the Numpy mumbo jumbo. Here I have code to plot intensity on a 2D array, and
I only use Numpy where I need to (pcolormesh expects Numpy arrays as inputs).

import matplotlib.pyplot as plt
import numpy as np

#here's our data to plot, all normal Python lists
