This begs for an analysis of the final graph.

Exactly. It looks fascinating, but it looks like there is no further explanation or exploration of the patterns, as if something was cut off.

Sure, but I think there's plenty of room for people to say "I found this pattern that looks really interesting!" without analyzing it further themselves.

If you look at the previous posts on the topic, this seems to be an ongoing series of posts.

It's bluer on top and redder on the bottom. So I'd say "reaching lots of squares requires being farther from the origin so as not to recolor"

It's bluer than red, so I'd say, "It's easier to visit new squares that old squares"
