feat: save visualizer html

[jaapschoutenalliander]

• Added save_html(grid, path) to visualizer.py — exports the grid as a standalone HTML file without starting the Dash server
• New html_export.py module handles HTML generation: embeds graph elements, stylesheet, and layout as JSON with Cytoscape.js
• Docs updated with usage example and parameter table; two unit tests cover default and non-default parameter paths

Looks like a nice addition. Haven't tested/viewed the HTML, but the code to maintain this doesn't seem to bad.

Maybe some of the setup surround the layout/stylesheet can be shared even more with the actual app. But if not, this seems fine to me.

Looks promising! This has been requested for quite a while I believe 👍 . I'll review later this week

I tested it locally.

The HTML only contains the graph. The top and bottom sections are not included. In the future we could look whether that is feasible/desirable too (but we'd have to move logic to the JS side instead of Python).

For now, nice addition!
