Over the years I explored a few ideas to display large DOM trees compactly on a plane (although with a focus on creating a map-like structure): - https://twitter.com/mootari/status/771375569497944065 - https://twitter.com/mootari/status/838031564458053633 and https://twitter.com/mootari/status/896809001295507457 - https://twitter.com/mootari/status/896806993524142081 - radial: https://twitter.com/mootari/status/853333975728828417 - 3d: https://twitter.com/mootari/status/896803311260749826 Would love to pick this up again and brainstorm further if you're interested!

Oh yeah, that would be really fun. I'd love to make this something that was really easy to plug into observable. (Maybe even a feature one day!) I think it greatly helps for debugging and teaching visualization. We should do it!
