I'm interested in drawing a treemap:
What is the easiest way to make one in Python? Is there a library that could produce such a graphic, given the proper input data?

There is a Treemap but it isn't in the python standard library.
Size distortion can happen when you need to show a greater number of pixels, where you can only optimize for size comparisons at one level of the hierarchy at a time. Usually, all the commercial treemap implementations used gutter borders to show the hierarchy clearly at the expense of size comparisons.
A Treemap diagram is an appropriate type of visualization when the data set is structured in a hierarchical order with a tree layout with roots, branches, and nodes. It allows us to show information about an important amount of data in a very efficient way in a limited space.
The SciPy cookbook includes an example using matplotlib, but without labels.
