"A Visualization Language for the AI Era", as a tagline, sounds weird.

I had the best success with popular and versatile packages like matplotlib and ggplot2 - even 1.5 ago (vide https://quesma.com/blog/which-chart-would-you-swipe-right/).

Now, frankly, my go-to visualization package is React, sometimes with a pinch of D3.js (e.g. https://p.migdal.pl/tree-of-tree/).
