From the nytimes.com, this graphic visually represents how average consumer spending breaks down, and the color code shows how much spending in that category has changed in the last year. For example, Gasoline is 5.2% of an average consumer's spending, and it has risen 26% from 2007 to 2008.
As far as I can tell, this is actually a treemap, but in a new shape. More details pop-up when you mouse over each of the individual shapes.
Thanks to Tony, for sending in the link.
