Radial Horizon Graphs: An Original?!?

The logical conclusion to my exploration of Horizon and Corona Graphs.  I've searched and can find no other examples on the "internets" of a radial Horizon Graph, so perhaps this is a first!

For your viewing pleasure, here are ten matches from Grand Slam Finals.  I hope the Radial Horizon Graphs have captured something of the dynamics of the matches that you wouldn't otherwise see when glancing at the score. I've provided a brief (unprofessional) "reading" of each graph, making the (perhaps unwarranted) assumption that there are more winners and forced errors being made than unforced errors.  In the next version of this graphic, or in the interactive version for TAVA, changes in momentum due to winners and losers should be easily discerned.

LEFT: Apart from the first few games of the first set, Kvitova dominated Bouchard.
RIGHT: Hingis was dominating until near the end of the 2nd set; Capriati had a strong finish.

LEFT: Navratilova and Evert were neck-and-neck in the first two sets; Martina dominated in the beginning of the 3rd, but Evert clawed her way back and took the lead at the very end, then lost.
RIGHT: Muguruza took an early lead but lost momentum; she began to recover near the end of the 2nd set, but it was too late.

LEFT: Safina was stronger at the beginning of both sets.
RIGHT: Sharapova was strong at the beginning of the 1st set; she lost ground steadily in the 2nd.

LEFT: Na Li almost gave up her early lead in the 1st set; she never looked back in the 2nd.
RIGHT: Notice that all three sets ended at 6-3; there are differences, but Cilic steadily advanced.

LEFT: Federer began and ended in control; Roddick lead throughout the 2nd set; the 3rd set was a bit of a seesaw, but Federer held; the 4th was definitive.
RIGHT: Wozniacki had a chance to break in the 1st game of the 1st set; after that point she couldn't win points fast enough to keep up with Serena.
