The New York Times is a leader in online, interactive statistical visualization.
Here's a recent example that statistically re-stacks exit poll results regarding how each state voted for Obama and Clinton during the just completed 2008 Democratic Party Presidential Primaries.
Choose by sex, income, race, age, income and education, and watch as each state - represented by a block - is re-positioned according to how close or how far each state is percentage-wise away from the interesection of the X/Y axes. Run your pointer over each state's block, too, to gather statistical data specific to each state.
New York Times Interactive Graphic
For those of you with further interest in what the New York time is significantly accomplishing, check out a May 16th blog by Jon Udell entitled A conversation with Gabriel Dance and Shan Carter about interactive graphics at the New York Times. This is a short blog prefacing an audio interview conducted by Udell produced by ITConversations and entitled Shan Carter & Gabriel Dance: Enhancing Online News Content (57m).
Without going into further detail, I have listened to this audio podcast (also available for free download via iTunes) and this is a fascinating interchange between Udell, Carter and Dance. It's much much of the nuts and bolts (still highly manual) that go into creating statistical visualizations that serve to connect ordinary people with data that they would otherwise be oblivious to.
I highly recommend downloading Udell's podcast to your iPod!
