Integration with VlConvert and VegaFusion #25

Open jonmmease opened 1 year ago

Hi 👋

I know this crate hasn't been active recently, but I wanted to reach out because I've been working on a couple of Vega+Rust projects that could potentially integrate well with this crate.

VlConvert

The first is VlConvert (blog post). This crate embeds the Vega and Vega-Lite JavaScript libraries in a Deno runtime to support the following operations (without a dependency on an external browser or node.js runtime):

VegaFusion

The second is VegaFusion, which provides the ability to automatically extract Vega transforms and evaluate them in Rust using the Arrow DataFusion query engine. This makes it possible for many Vega-Lite charts to work with millions of rows as long as they include some form of aggregation.

Both of these projects are wrapped in Python to support Altair, but they could also be used directly from Rust, from a project like vega_lite_4.js.

Those are two great project ! I think this could be a great integration with Procyon. This crate was meant to be an Altair like for rust
