GraphViz with Stencil

Integration guide for teams shipping diagram rendering in Stencil.

GraphViz usage guidance

Best for

  • Dependency graphs
  • Directed acyclic graphs
  • Infrastructure relationships

Syntax tip

Declare rank direction early and keep node identifiers stable for diff-friendly updates.

Quick start

Call the ChartQuery API from your Stencil stack and return rendered GraphViz output to the UI.

Recommended flow

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

Typical Stencil integration path: /server/diagram-renderer

Stencil implementation checklist

  • Add a server-side rendering endpoint
  • Validate and sanitize diagram input
  • Cache rendered output for recurring requests

GraphViz source example

digraph G {
rankdir=LR;
app -> api;
api -> db;
}
