I'm a big fan of VisX for the level of control it gives.
I guess it’s specifically a react library, but it’s such a sweet spot of control and built-in convenience. Having all the annoying stuff like curves/axes/scales/shapes handed to you in a pretty un-opinionated way is really nice.
I was at a startup for a few years and I built all of our client’s dashboards in visx. I loved it from the first minute to the last, and have almost no complaints. And there are few few libraries I can say that about!
