Is this just fiber distance between each datacenter? The coloring makes it seem significant, but from the distances it kinda just looked like ever < _km (100ms) was green, everything between _km(100ms) and _km(200ms) was orange, and everything over was red.

I'm not sure what you're wondering here. Of course physical distance is going to be a dominating factor, but this is measuring packet transit times. The speed of light over half a great-circle is only 67ms or so, ot maybe 100ms considering velocity factor in fiber, so clearly there's more to it than just distance. We can talk about what those other things are, but we both know they exist, right?

Basically yes, as distance is the most important factor when it comes to latency.
