This is fascinating stuff. I've been working on similar tooling, but with a totally different approach/perspective, since my team isn't at all interested in sequential data visualization, but rather sequential technical illustration. So it's fun to see what sorts of things are easier/harder about making this stuff approachable to non-coders when you design it around some expectation of data/stats literacy VS arts/visual communication proficiency.

This is really neat. I feel like I'll have to watch this one a few times at least to really appreciate what they've done. Immediately, though, I love the attention to graphic design.

Not so hot on this one.
