Well, I like it. Yes, it requires some time, but overall makes a lot of sense as a comparison. I would have left the 794 cities part out of the graphic to see more clearly the difference between the USA and outside the USA, but I guess you wanted to show it for some specific reason. That part was the only one I had to “guess” by adding the n value for USA plus the one for non-USA cities.
