See what your dependencies call most
Every dot is a function, placed by how often it’s called in production and how much of that runs inside a loop. Put on a project lens, say Kubernetes, and the map redraws to what that codebase calls, with its own loop shares. Search, filter, click through to any function.

Colour is heat, how many of a function’s production calls land inside loops. The ringed, labelled functions run both hot and often, which is where a profiler is most likely to agree. Static counts aren’t runtime cost. Snapshot 2026-W40.
