Chord2SVG is now live on GitHub. It is a rendering engine that computes engraving-ready chord notation directly in SVG, with collision-aware notehead placement and optimized accidental spacing.

The project includes a web preview for quick testing, a CLI for batch engraving, and a React component for integration inside other tools. The goal is consistent output without the overhead of traditional notation software.

Release highlights

Multi-pass collision handling for dense chord clusters.
Automatic clef detection and ledger line rendering.
CLI batch export from JSON input files.
React component for programmatic SVG access.

Quick start

npm install
npm run dev
# http://localhost:3000

npm run cli -- --input inputs/chords.json
