This is beautiful. Tableau look out.
For simple data visualization with animations, e.g. Flourish is a good option, but it's limited without enterprise access. You can find examples here: https://flourish.studio/examples
So, I really enjoyed Observable's new documentation and tutorials which actually show, not tell how to use the cool examples with your own data.
(Note: I really dislike apps that only have video tutorials. It's hard to follow along and not get bored or lost. Sorry about this rant in advance, and thanks for all the producers who offer clear documentation as text or reasonable guided tours.)
