Tennis is already one of the most high-tech, closely monitored sports in the world, from high-speed cameras that swoop around the court to digital refereeing that can see if a ball traveling at 150 miles per hour glanced a line by a millimeter.

This is a ton of data--there are thousands of shots per match, moving very quickly. But that quantity of data makes it easier to see larger patterns, like where shots tend to land or where they had the most impact.
Check out a video of how the visualization was made below:
