XKCD's megachart on money

The latest XKCD is a monster infographic on money, called "MONEY: A chart with almost all of it, where it is, and what it can do." It's a fascinating, astounding piece of work, including everything from the average cost of fish ownership to a list of the world's billionaires to a worker/CEO pay comparison to a breakdown of US tax-deductions to American government spending to the cost of major recent disasters and much, much more.
