Diagrams Playground is now live!

[mingrammer]

We added a browser-based Playground for Diagrams!

https://diagrams.mingrammer.com/playground/

You can now write Diagrams code and see the rendered diagram instantly in your browser — no Python, Graphviz, or Diagrams installation required.

The Playground is built entirely on WebAssembly (WASM). It runs the real diagrams package in the browser via Pyodide, and renders generated Graphviz DOT using Graphviz WASM. There is no backend for executing your code.

Some useful features are included:

• Live preview as you write code
• Node search and autocomplete
• PNG / SVG / JPEG export
• Shareable links
• Examples gallery
• Light / dark theme
• Pan & zoom canvas

Try it out and let us know what you think!
