Treemap is so much more proportionally intuitive than bar plots, which is the aim of visualization; to enable humans to rapidly perform unsupervised learning on complex data.
It would be nice to be able to zoom on a treemap to see smaller points. Like my friends in Iceland.
It would be nice to fit more points in the treemap. It fails after a certain number of points, so I can’t use this for dynamic user input because they will think my code is bugged.

If there is only 1 parent, it would be nice to toggle its presence or have examples in the docs on how to change its color. The parent’s color distracts from the points.
