The second Visual Analytics Science and Technology (VAST) contest was held in conjunction with the 2007 IEEE VAST Symposium. A synthetic data set was created containing a known scenario with embedded threats, therefore providing ground truth. Participants used visual analytic tools to explore the heterogeneous data collection and find the evidence of illegal and possible terrorist activities in the data. We describe the contest and the evaluation methodology, then provide details on the results and the two winning entries. Lessons learned are reported from different points of view: contest committee, participants, judges, stake holders and other researchers.
