A Grafana alternative with an MIT (or similar) license.

I'm shocked that Grafana is really the only OSS game in town for user-customizable realtime visualization.

p.s. I would love nothing more than to be proven wrong.

Out of interest, what exactly do people use Grafana for? Is it always monitoring infrastructure/ systems or is it more general purpose than that? What is special about it?

I come previously ran an analytics team and I work on an open source BI tool (https://github.com/evidence-dev/evidence) but I have never actually used grafana or come across it when talking to other "business analytics" folks. Everyone in my world is just using tableau or looker or jupyter notebooks.
