Interactive statistical graphics

In the last few years, interactive data visualization seems to have really taken off. Some Google counts:

• "visualization": about 53,300,000
  
• "interactive visualization": about 243,000
  
• "interactive data visualization": about 28,100
  
• "interactive statistical graphics": about 362
  

(By the way, "Google metrics" are an interesting topic in themselves, and certainly there are all kinds of methodological questions about their use. See g-metrics.com for some longitudinal data. But they probably give a rough indication. To get a sense of scale, I turned off Google's "safe search" feature and did a search for "sex". Result: about 224,000,000.)

Check out this remarkable interactive visualization on The Secret Lives of Numbers.

For the last few years, the New York Times has been producing quite impressive interactive statistical graphics:

• How Class Works
  
• The New Brooklyns: Demographics
  
• Target: Ground Transportation
  
• A Look at 1,000 Who Died
  
• U.S. Election 2004: A Divided Electorate
  
• The 2003 California Recall: Results
  
• How They Die (Congo)
  

I'd be very interested in comments about this. Which ones do you like or dislike? Why? Do you know of other interesting examples?
