Would it be feasible to implement something similar or integrate with VegaFusion. It is a serverside accelerator for large datasets visualized with Vega

I have started a discussion on VegaFusion about this: https://github.com/vega/vegafusion/discussions/499

We would need two things:

  1. To support a to_vega conversion on VegaLite through vl-convert, something that can also happen with the png/svg generation: https://github.com/livebook-dev/vega_lite/issues/80

  2. Add bindings to VegaFusion and a mechanism to export Polars to Arrow IPC (ideally zero copy)
