Help me find a pseudo-cartogram of the world's largest cities.

Help me re-find a cartogram-like picture of the 100 largest cities by population.
A few months ago I saw a chart of the world's largest cities (maybe the cutoff was all cities with over 1 million people, maybe it was the 100 largest). The picture was a large rectangle and the cities were rectangles as well. Tokyo was in the upper-left with a bajillion people (35 million ish), then the next 5 or so cities had in the 20 millions.
There may have been color coding to indicate what country of the world they were in.
I might have seen a story about this chart on Lifehacker, the Freakonomics blog, or maybe just reddit. Can't remember, and I'm apparently not Googling for the right keywords.

I think you are looking for a "Treemap". (more)
Many eyes has quite a couple of these, and tools to customize your own.
Thanks for the question btw, I had not discovered these instant visualization tools before.

Response by poster: It was definitely a treemap, thanks.
If you're into visualization tools, you might be interested in the Ted Talk by Hans Rosling (it's an amazing video regardless), and his site "Gapminder," which supports data mashups in a similar way.

Response by poster: It was clearly by Urban Area Population, rather than City Population.

Response by poster: This is very similar, but there were many more cities.
There may be so many treemaps of cities out there that searching for a specific one I stumbled upon a few weeks back is a bit of a lost cause.
