In+ersec+ion for Spatial People

That's the name of a recent O'Reilly article, Visualization deconstructed: Why animated geospatial data works.

From the article: "Sebastien shared a great quote, attributed to Paul Butler, which read: "Visualizing data is like photography. Instead of starting with a blank canvas, you manipulate the lens used to present the data from a certain angle." [...] Central to the impact and effectiveness of these designs is the simple animation of the data over time. Some exist with just a play/pause button; others have more interactive options to control the speed, flow and progress of the timeline. For the viewer, there is palpable excitement when anticipating how the patterns will evolve; when the data spread will increase or decline; when the data activity will speed up or slow down; and when it will pop up in new, previously uncharted territories."
