Thank you for pointing out! Should be gone now.

Thank you for pointing out the lag, it should be gone now.

There's also Voyager which generates Vega-Lite spec prediction based on provided data:

https://github.com/vega/voyager

I made a small clone just to understand the inner workings of it: https://ellx.io/matyunya/simple-voyager-clone/index.md

Here's my very basic attempt at ggplot-like API on top of Vega-Lite: https://ellx.io/matyunya/plot.

There's also Vega-Lite API for producing spec JSON with more typical chaining calls: https://vega.github.io/vega-lite-api/

Nice. Feel free to send us a pull request to add your Voyager clone to https://vega.github.io/vega-lite/ecosystem.html.

I'd be honored!

Shameless plug! https://ellx.io/ is a programmable spreadsheet with extended JavaScript for formulas (plus operator overloading and automatic async resolution)
