I also built a complete data visualization library using the core package which is available as @ripl/charts. And yes, you can even render the charts to a terminal with about a 2-3 line code change :) (see the terminal demo)
Docs are available here: https://www.ripl.rocks Demos are available here: https://www.ripl.rocks/demos Charts are avialable here: https://www.ripl.rocks/docs/charts
I've also built an interactive playground you can use to play around with it in realtime without having to install it from NPM etc. The playground is available here: https://www.ripl.rocks/playground
The core library is quite stable and I'll likely publish v1 in the coming weeks. The charts, 3D, and Terminal packages are still very experiemental.
I'd interested to hear what you all think of it.
