This looks beautiful, I don't do data viz in Python so I don't have a use for this. I do mostly web dev in Python, but wow it looks amazing!

I'm really surprised (and almost not) to hear the UI is in TypeScript, did you use a specific web framework like React by chance? The UI looks really nice to me.

Thanks!

The initial prototype did use React, but the overhead in certain cases soon became an issue. It got replaced by a custom virtual dom implementation (coincidentally quite similar to Atom's Etch), but debugging complex updates remained an issue. Eventually, it ended up in a place quite similar to vscode: no frameworks and a handful of "core components" (eg: a virtualized list view)
