Lattakker: a spreadsheet of TypeScript cells (and a little board game) built on maxGraph 0.25

[springyworks]

Hi maxGraph folks! I wanted to share a project that uses maxGraph for something a bit unusual, in case it is useful or fun to see.

Lattakker is a spreadsheet where every cell holds a small TypeScript program, plus a board game on top. It is made for children learning to program. Everything runs in the browser; there is no server.

How maxGraph is used:

• The whole sheet (headers, cells, merged blocks) is a maxGraph graph with HTML labels, so cells can hold live Monaco editors, animated SVG drawings, plots and tile grids.
• A block can contain a grid of tiles with text and keyboard input (there is a terminal-chat example in the Examples tab).
• Overlays (selection, rubber band, address tags) are drawn by maxGraph on its UI layer.

Try it (nothing to install): https://springyworks.github.io/lattakker/
Source and a long manual: https://github.com/springyworks/lattakker

Oh yeah you can use its internal mcp , it has a built-in mcp router , so fun.
Feedback is very welcome: what looks wrong, what you would do differently with maxGraph, anything.

Thanks for maxGraph!
