Hoping to pick everyone's brains! I'm wondering if anyone has created a ggplot extension for a bubble chart where the bubbles/points are clustered together. I've seen this style of plot done frequently in D3 but never in ggplot:
I'm not looking for the interactive elements here, just an extension that can position points together. If it can be done with points, I could potentially implement the positioning with ggflags too (which would be the ultimate goal here—although if it's too hard, I'd probably just do it in D3).
