We likes powerful data visualization. After all, some of the best examples take data to a new level and help move people to action.

But not all applications are worth applying data viz to. In this video, Eric Rodenbeck, founder of design studio Stamen takes us through a few applications that do seem to make sense.

Based on live datasets, these involve Flickr, web 2.0 real estate site Trulia, and a SF Yellow Cab mapping initiative called Cabspotting.

One part we like is when Eric says that they’re not interested in the underlying technology, even though one of their team has developed the underlying software (and even better, made it open source).

You’ll find a much better writeup here, courtesy of Scribe Media, the folks who produced the video (and more besides).
