node new_id 'New label' below anchor — placement is relative, so the solver re-flows the whole diagram instantly.edge a -> b 'your label' — labels are the fastest way to carry rates, protocols or percentages.below to right of rotates a branch sideways without touching any other line.Declare each box with node, connect them with edge, and state one position per node relative to another. 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.
