Is this similar to deepscatter?

I'm a huge fan of altair, it has great docs, great declarative syntax, and makes it very easy to produce beautiful interactive visualizations. My only gripe would be, it starts to chug when it comes to plotting larger scatter plots, which is to be expected.

How does this compare to deepscatter, it looks like it is trying to achieve the same thing, or maybe avenger + vegafusion would be a more similar analogy?

Hi @AH-Merii, Avenger by itself is currently just a renderer. I played with integrating it as a renderer for the Vega JavaScript library, but the performance improvement wasn't as significant as I had hoped due to other parts of Vega not scaling well to large scene graphs.

I'm still mulling over where to take avenger. See also discussion in #83. One possible direction is to use VegaFusion and Avenger as the foundation of a new native Vega implementation, with no JavaScript involved. Feel free to weigh in here or there about the direction you find most interesting!

Thanks for getting back to me! I definitely think eliminating JS in favour of more performant backends is the way to go in terms of handling much larger datasets. For now, I actually precompute most of my aggregation operations in polars and feed them into Altair; the reason I am not using VegaFusion yet is that it is not yet supported by marimo . My main limiting factor remains the renderer, which is why I was looking into Avenger in the first place.

Does Altair's JupyterChart not work in marimo? It's based on anywidget so I had assumed it would work. If you enable Altair's "vegafusion" transformer in combination with JupyterChart the aggregations will be performed serverside.

But, as you said, that doesn't help much with non aggregated charts.
