idk it's my first time (kind of) trying to do dataviz, I thought the original post was super interesting but like other comments said, it was hard to read.
I think in a way it's mostly because defederation is complex to show as links, since it is the break of said link, but hopefully this type of graph is better ?
you do lose the "group" of instances view, though (and also I did not bother with per instance MAU as raw number + percentage, or sofware used)
let me know what you think!
Chiming in as the OP, I used rawgraphs.io which only has 2 colour palettes for this amount of data (the first one only covers 7 colors the rest becomes grey), there's the option to pick your own colours and I considered picking colours from instances logos so they would fit. No idea if that would have been better for accessibility. In general there are colourblind-friendly colour palettes suggestions out there and I should have checked them first!
