Scoring visuals like this have long been offered for basketball, but as far as I can tell, this is new to tennis. Below are the men's and women's championship matches.
The site says this feature was created in collaboration with IBM; I wonder if Martin Wattenberg and co. in the Visual Communication Lab have anything to do with this.
Tennis visuals are getting better every year. Although it is often criticized, I think the technology that tracks the exact path of the ball is incredible, and this year a visual has been added showing, on any given point, a player's total distance traveled. (On one point, Roger Federer traveled something like 67 yards(!); I would love to know how far the players travel in an entire match.)
