Vega3 support in JupyterLab

[Dave Dixon]

In the last few days, the Vega3 extension for JupyterLab seems to have disappeared. I was able to install it on my machine, and not long after had a colleague try it and he was getting errors. It appears the Github repository has been replaced with a Vega2 extension, and I gather from looking through the JupyterLab Github issues that this is planned, with Vega3 support becoming the default in JupyterLab. But it doesn't seem to be in the current release. Is there any way I can get my colleague up and running with Vega3? Thanks.

For the 0.31 release it was a separate package:

https://www.npmjs.com/package/@jupyterlab/vega3-extension

That package is still available on npm, so you should be able to
install it on 0.31 with:

jupyter labextension install @jupyterlab/vega3-extension

In JupyterLab master and moving forward it is built into JupyterLab
itself, so no additional extension is needed (but vega2 will be a
separate package moving forward).

What version of lab are you using? How did you try to install/use it?
