Standalone Mermaid Renderer

This Flask app renders Mermaid text directly in the browser. It does not use Harmonia, product packs, or draw.io. You can paste Mermaid text manually or simulate an AI/API call.

Mermaid text

Simulated API prompt

The /api/generate route is a safe stub. Replace that logic with your real AI or API call later.

Rendered output

Mermaid renders to SVG, which behaves like a crisp image in the browser. You can also export the SVG from the DOM later if needed.
