In 2011 I was part of a panel at SXSW Interactive on the topic of geotemporal visualization, i.e. displaying data with both geographic and time components. Along with my fantastic co-panelists (Irene Ros, from IBM Research; Ryan Shaw, from UNC; Ana Boa-Ventura, from Media Shots; and my brother Adam Rabinowitz, from UT Austin), I presented a range of visualization techniques and discussed the potential, challenges, and risks of different approaches.
You can see my slides here, including a set of interactive visualizations I produced for the presentation using a range of tools including Protovis, Processing, and Tableau. Note that you may need a modern browser to see some of the examples.
