Altair is superb. Have used it a lot and it has become my default visualization library. Works in VSCode and Jupyter Lab. The author has a great workshop video on youtube for people interested in altair. I especially like the ability to connect plots with each other so that things such as selecting a range in one plot changes the visualization in the connected plot.

One possible downside is that it embeds the entire chart data as json in the notebook itself, unless you are using server side data tooling, which is possible with additional data servers, although I have not used it, so cannot say how effective it is.

For simple plots its pretty easy to get started and you could do pretty sophisticated inter plot visualizations with it as you get better with it and understand its nuances.

Awesome to hear that you like Vega Altair. With the recent integration of VegaFusion you don’t need to embed the data in the notebook anymore and I’ve found Altair to scale quite well. Give it a shot.
