Rick points to more fun places for Visualizing data
Will notes that Style.org has some incredibly neat pages that show different ways of visualizing data. I agree.
Kudos to Will, who poked around after I pointed out the attempt at determining the airspeed of an African swallow (unladen, migratory) and found a few other gems. Style.org is the work of 13pt, where Jonathan Corum is the principal. Very cool stuff.
