Quick start

Call the ChartQuery API from your Astro stack and return rendered Vega output to the UI.

Recommended flow

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

Typical Astro integration path: /server/diagram-renderer
