This is a great lecture by Hans Rosling, interesting and communicative visualizations, and he really knows how to show the story in the data. It's only 20 minutes and worth your time on two levels - learning something new and seeing someone good at presenting information.
Trulia, a real estate search service, has an interactive map of US homes animated based on when the homes were built. It's fun to play with. The search service (the first link) has a well-designed navigation and display interface, better than others I've used. Worth looking at to see how information displays can be made interactive.
Love this video making the rounds of housing prices as a roller coaster. You really notice the big rises and falls in the market when you experience them "firsthand".
Exactly what it says, this is a periodic table of visualization methods. Before this I never would have known what a Nassi-Shneiderman diagram was. It will be nice when Visual Literacy gets their online tutorials up. As to the periodic table, I like it!
I like the design of this graphic from the New York Times comparing the ginormous annual cost of the Iraq war to what we could have spent the money on instead. Pretty amazing what the War That Would Pay For Itself has cost us. (click thumbnail for a larger image).
I also found out that all the libraries in my county will be closing due to lack of funds. Seems the way to pay for the cost of bombs is with our children's education. (although the direct cause of this cut is because of a sleazy federal budgeting rule where clearcutting all our public forests gives us library, police and school money; however, funding to cover the cuts would be possible, were it not for the giant sucking sound that is the Iraq war)
