Nice, but is it data visualization?
I like this video (found via Flowing Data) quite a bit, especially the reminder about the fragility of the atmosphere and curve of the horizon line. But is this data visualization or is it fact marketing? Data visualization should take data points and reveal patterns unseeable (or hard to see), or coax a story out of a perceived bunch of noise.
Vizworld just posted an interview with Edward Tufte which is a nice reminder of first principles of data visualization:
Not much has changed since Tufte began offering the Presenting Data And Information lecture years ago, other than a fourth book and a couple of new examples, but not much has to change when the point is returning to the first principles of information design: make wise comparisons, show causality, employ multiple variables and, above all, focus on the content. This point was driven home for me early on in the lecture as I internally formulated a question on one of my favorite topics: “How will the techniques presented in this lecture help me better represent 3d digital cities?” As if my mind had been read, the answer came: “Don’t ask how visualization techniques can help display data. Ask how data can be best represented.”
I like that it’s a statement of positive principles — show causality and comparisons, seek out complexity and richness, etc. — rather than the anti-prescriptions that are often associated with Tufte (avoid chartjunk, eschew Powerpoint).
