The Interactivity of Altair Data Visualization

The ability to add custom tooltips and then have those tooltips have like F string style formatting as well as pretty excellent. And one of the other things that's interesting about Altair is it does try to infer different aspects about your data. So if you want to just focus on, let me pull out just in this case, it's got like agricultural finance government type of spending or something. You can just say, I want to just see the educational and health and click that and it highlights that sort of separate from the rest of them.
