Rust → WASM · WebGL2 · renders on the visitor's device
The GPU renderer for large hierarchical graphs.
graphigo draws graphs the size of a codebase — every service, file and function at once — laid out by a deterministic circle-pack that is computed once per change and never oscillates.
How it works
Still by construction.
Not a force simulation
Children are packed at fixed positions and the container is sized to exactly enclose them — recursively, once per structural change, never per frame. The layout cannot oscillate, and containment is guaranteed by construction.
Depth you can read
Colour encodes hierarchy depth. Size encodes child count, in four discrete steps — never a continuous scale nobody can read back. Nothing is hidden: every edge is drawn, and parallel edges bundle into one arrow with an ×N label.
Drill without losing your place
Double-click a node to open it into a container and keep going — the camera fits the current level, the breadcrumb carries the path back. From the whole system down to a single leaf.
Layout plugins
A layout is a function.
Structure in, positions out. Layout plugins are pure and deterministic — the renderer owns the transitions and animates them. Want a force layout anyway? Fine: run it to convergence inside your plugin and return the settled positions. The oscillation stays out; your layout gets in.
The plugin spec is a single self-contained document, written so you can hand it to an LLM and generate a working layout. A validation harness checks containment and determinism — a generated layout proves itself before it ever renders.
