Want to see a cool example of data visualization? This case study video that shows how the Tampa Police Department used Microsoft Surface to help law enforcement and emergency response crews provide safety, analyze what was going on and communicate better during the Super Bowl. The Super Bowl attracts millions of tourists and the Tampa Police Department was looking for a method of processing incident and event details in a manner that was intuitive and easily understood.
