Dependency graph treemap visualization! :)

Shows disk space used per dependency.

Instructions

1. Clone repo
2. Run the bash script on a derivation, eg ./deps.sh /nix/store/z49g31nnd5hkf2di6gp693mlsp23xdgh-python3.10-remarks-0.3.10
3. Open the html file
4. Open the generated JSON file

Get derivation path for a flake build

If you have a flake that builds a package, you can get the path with nix build .#my-derivation --no-link --print-out-paths

What the heck is a treemap?

Introduced by Ben Shneiderman in 1991, a treemap recursively subdivides area into rectangles according to each node’s associated value. D3’s treemap implementation supports an extensible tiling method: the default squarified method seeks to generate rectangles with a golden aspect ratio; this offers better readability and size estimation than slice-and-dice, which simply alternates between horizontal and vertical subdivision by depth.
