@knowvah/dot-engineGraphviz, in pure TypeScript

DOT in, SVG out — no C. No native Graphviz binary, no WASM. Pure TypeScript, runs in the browser.

Faithful to C Graphviz

A line-by-line port of the canonical C implementation. The dot engine matches the native binary to a tight deterministic tolerance (±0.01 on coordinates, exact non-numeric content) on the golden corpus.

Browser-native, zero runtime deps

No C — no native Graphviz binary, no WASM port, no rendering server. The layout engine itself is TypeScript — bundle it and ship.

All eight layout engines

dot, neato, fdp, sfdp, circo, twopi, osage, and patchwork — rendered to SVG.

Programmatic layout + geometry

Don't just render — read back computed node positions, edge splines, and cluster bounds as a plain JSON-serializable snapshot via getLayout(), no -Tplain parsing required.

Try it

The editor below runs the actual library, in your browser. Edit the DOT on the left; the SVG updates live.
