"How the Giants of Finance Shrunk, Then Grew, Under the Financial Crisis" [nytimes.com] displays the market capitalization of 29 of the biggest financial firms on September 11, 2009.

The "animated treemap" graph demonstrates the overall and relative changes in market capitalization over time, since the stock market's peak in October 2007. Since then, Wall Street's landscape has been permanently altered, as financial giants crumbled under the weight of the financial crisis. While most firms are still considerably smaller, 2 banks (i.e. JPMorgan Chase and Well Fargo) are actually slightly larger than they were at the market's peak.

Hello,

You can also see Kap Lab TreeMap that can be used in the financial industry.
It is a Flex AS3 component which can be use to display more than 4000 nodes in less than one second. It also represents many features like filtering, drilling into the data and a legend to represent the data displayed into the component.
Please see the demo on this link:

While I have to admit the treemap is cool looking, its use here in this graphics is not very good. All I can see from this graphic is that the financial industry is shrinking, which is nothing new. I can't really see, for example, how Morgan Stanley shrinks over time. As one of my co-worker suggested, this data set could be presented better as a simple bar chart with the initial amount grayed out. As the time changes, that initial amount stays, while the bars shrink in relation to the initial amount.

I understand that many people feel the need to show more complex visualization for the WOW effect, but in the end, it is all about the data.

Fine mapping you have done and you have done shrinking as well. It's necessary I think. Keep it up...
