GameSetMap's GameTree now live with data from the Match Charting Project...

"Game Tree" is a depiction of Point Progression for a selection of games within a tennis match or across a series of tennis matches; it is a Sankey Diagram and possesses the "Markov property", meaning that the set of future "states" that are possible are constrained by the current "state", the point score at any moment in a game.

At the base of every tennis statistic there are Shots; many Shots. And every shot has a multitude of attributes that can be captured. Using a frequency-based visualization in combination with time-series views makes it possible to create collections of data elements (Shots) and visualize their distribution throughout a Tennis Match.

The Match Radar is intended to provide a compact visual comparison of the key statistics for players of a tennis match. This is in contrast to the Points-to-Set, Horizon and Radial Horizon charts which aim to depict the dynamics of a match with respect to the scoring of each set.

The Match Radar enables a quick assessment of whether and how one player dominated another, whether a match was lob-sided, and where players differed on key statistics.
