Looking forward to this feature! Since vega-lite is converted into vega, it should be fairly straightforward?

There's a similar issue #483 where the use of vega-embed is proposed.

I'm willing to look into it and push a MVP PR by the end of next week to discuss it further if nobody has picked it. @tvst if you have any concerns or tips on how you would architecture that I'm all ears :).

You could probably pass a Vega spec to the Vega-Lite view and it should almost work since the Vega-Lite component used Vega-Embed (https://github.com/streamlit/streamlit/blob/develop/frontend/src/components/elements/VegaLiteChart/VegaLiteChart.tsx#L268).

@domoritz I dont have a working example right now, but when I tried this it did not work

That's why I said "almost" ;-) But the code paths should be very similar if anyone is going to implement support for Vega.

Hey @mmcguffi,

I've got a minimal implementation on a branch (just copied and edited the VegaLite code path). Do you by any chance have some Vega spec you want me to test ?

Hey @andfanilo -- sorry for the delay! This is the example I had previously try get get Streamlit to render: https://vega.github.io/editor/#/examples/vega/donut-chart
