C4P co-sponsored the Cart Lab Design Challenge, which challenged more than ten teams of students at the University of Wisconsin to develop new visualizations to facilitate the communication of trends in multidimensional spatio-temporal data, specifically data from the N. American fossil record. Twenty students participated and self-organized into working groups of 1-4 people. Each developed an independent and creative solution. Students had 10 hours to come up with an initial design concept and one week to develop a pilot visualization that they then presented. Examples of these visualizations can be viewed here.
