The Game Tree Interactive [] visualization by Damien Demaj analyzes the more than 600 service games played by Rafael Nadal during the Grand Slams, Masters 1000 and World Tour Finals in the year 2013. In particular, this visual summary shows where Nadal’s history breaking season was won and rarely lost, point by point.

Each point is color-coded to reflect the momentum in each game: blue represents positive momentum, while red denotes negative momentum (and white is neutral). Accordingly, a match that was dominated by Nadal is highlighted with a thicker, outside flow that passes through the ‘positive’ points of the Game Tree, while the opposite shows a flow that enters more ‘neutral’ or outside ‘negative’ points.
