I've been using Recharts [1] lately. It offers many different chart types and has a high level interface that makes it easy and quick to use for basic charts. If you want to customize you can still do so because almost every part of a graph is composable. (I have no affiliation)
I was looking for a lib like this 2 weeks ago and I've never heard about this one... Looks like it's the most stared repo and it's actively maintained, but the Github link is not on the first page of Google with the keywords "react chart". (Edit: the "official" site is in 6th position, I've probably missed it or didn't scroll up to it)
Finally I've been using React Chartjs 2, based on Chartjs 2.
If I'm looking for a library now, I start the search on github, not Google. The github search can be filtered by language and sorted by stars, among other things.
Obviously not every project in the world is on github, but it's usually much more efficient to start there, rather than Google.
