I usually get very angry at the excessive use of animations everywhere, so I expected that this would give me a nice hit of righteous indignation to top off my afternoon. But this is a fantastic use of animation. In a UI like this, animation is great to helpfully draw your attention to where it’s needed and give you some indication of why you should look there. Very nicely done!

Three.js + OpenAI or Claude do almost everything for this purpose. I use it to visualize complex things like Raft groups and node states in multi node clusters for execs and C-levels. A simple library of styles and standard prompt are more than enough.

Why not put these in the HTML instead of as videos?
