Nice post - treemaps are great!

My friend and I made a codebase visualisation tool (https://www.codeatlas.dev/gallery) that's based on Voronoi treemaps, maybe of interest as an illustration of the aesthetics with a non-rectangular layout!

We've opted for zooming through double-clicks as the main method of navigating the map, because in deep codebases, the individual cells quickly get too small to accurately target with the cursor as shown in the key-path label approach!

If anyone's interested, this is also available as a Github Action to generate the treemap during CI: https://github.com/codeatlasHQ/codebase-visualizer-action

Hijacking top comment to link TreeSheets. It seems to have been designed for note taking using treemaps.

What an amazing tool! Certainly going to integrate into some of my codebases. I am actually fascinated by your charts, would you mind sharing which library did you use? I would love to use that in some of my personal projects.
