I think many folks are underutilizing or underestimate the power of HTML.

There's been a few of these things on the front page lately. Including false "whiteboards" that are DSL abstractions over things like React Flow...

I've done quite a bit with Excalidraw MCP and the models had to deal with a lot of JSON data and estimating/computing with bounding box and pixel point numbers.

But with HTML, the agents get the natural semantics/styling capabilities and basically zero abstraction. The recent models can draw exceptionally well any form of logical/conceptual/flow diagram.
