Paste the source from this page into the official playground and it renders immediately.
Yes — the source is free to copy, modify and ship in docs, READMEs, books or client decks. No attribution required.
Render in the playground and export SVG, or run it locally: npx reladraw file.reladraw -o out.svg for CI-friendly builds.
