  Check out mosaic from uwdata which works on top of Observable plotOr plotly-resampler which works on top of plotly and uses the rust package tsdownsample to aggregate on the 4pixels per pixel shown level (to make antialias work)the grammar of graphics approach really is a great abstraction, and I'd love to see xy work in that direction

  I’m not convinced GPU acceleration is a meaningful advantage for most charting use cases. Most dashboards don’t render enough data for it to matter. Once a chart is dense enough for rendering to become the bottleneck, it normally is already be too crowded to be meaningful. Zooming can justify supporting larger datasets, but sampling/viewport culling and level of detail often avoid drawing unnecessary points...

  Interesting approach to large scale visualisation. Moving reduction into Rust and sending screen bounded data to WebGL seems much more sensible than pushing millions of raw points into the browser. How does it perform with real time updates? I am assuming it is much more performant? Any plans for a prod deployment?

  Interesting; how do the examples compare to datashader?Edit: for my use cases, I use napari (~1e7-8 points) if I need true interactivity; otherwise, datashader/holoviz, or even just fast-histogram's 2D histograms work.For extremely large point clouds, these caveats[0] still apply. It irks me when people make dense scatterplots without any indication of just how dense some portions are.Still, if it can indeed handle 1e10 points, that's pretty impressive.[0]: https://datashader.org/user_guide/Plotting_Pitfalls.html

  it's possible to render data out-of-core with XY, allowing it to render the entirety of OpenStreetMaps (that's 10,742,674,832 nodes!) with sub-second pan/zooms. it's a bit difficult to host online but you can try it out locally: https://github.com/reflex-dev/xy/tree/main/examples/osm

  This is awesome, can easily see this becoming a standard library. Can't wait for the 3D and volume visualizations.

  been stuck on matplotlib for centuries, academia loves such a change

  how does this stack up to evilcharts? my main use case is mapping out data onto frontend, and there are a lot of great libraries out there

  I misread it as ‘Chatting’ library and I was so confused on the GitHub page.Love rust as the impl.

  Great, Rust and Tailwind CSS two of my favorite things in one.

  absolutely fantastic.

  no support for native GUI?

  super cool!
