SeqDiag with Lit

Integration guide for teams shipping diagram rendering in Lit.

SeqDiag usage guidance

Best for

  • General diagram rendering
  • Programmatic documentation pipelines
  • Automated visual generation

Syntax tip

Keep SeqDiag source deterministic and reusable across environments.

Quick start

Call the ChartQuery API from your Lit stack and return rendered SeqDiag output to the UI.

Recommended flow

  1. Store your SeqDiag source in code or markdown.
  2. Send source to a server-side endpoint backed by ChartQuery.
  3. Render returned SVG/PNG in Lit pages and docs.

Typical Lit integration path: /server/diagram-renderer
