As someone who's been building small projects with these kinds of libraries for years now, https://x6.antv.vision/en is absolutely incredible. All the antv libraries, especially when combined, are a vast distance ahead of anything else (most importantly in their conceptual foundations and design), and I highly recommend playing with them.
"Our broader goal in writing this up was to illustrate some higher-level TypeScript features and type-driven design patterns in the practical context of modern web development."
Is type-driven design a think? For me it's just development ...
The one thing that I always wonder about things like this which is basically Figma or Miro is how you persist / store the coordinate of the nodes given the user might have different screen sizes or resize their window etc.
the screen, or rather whatever container is rendered on the page, is just a viewport to an underlying canvas. The canvas can be zoomed and panned, and the focus of the panning and level of the zoom can be synced across machines. People with different size or shape viewports see slightly different cropping, but they are looking at a synchronised canvas through that viewport.
For anyone intending to use this in production, note that it is inoperable to people who can't use mice (which can be caused by any number of disabilities or conditions).
