Field notes
The workflow is organized as six stages—prompt, draft, IR, render, export, and ship—rather than treating the diagram canvas as the source of truth. Its sample document names an API gateway, service, and database, while POST /api/v1/render returns SVG from a schemaVersion 1.0 payload. The site also separates renderer input from React Flow state and stringified SVG, making the canonical document the stated interchange layer.
