Fig. 8: Frequent shape graph edges.
From: Shape graphs and the instantaneous inference of tactical positions in soccer

Edges appearing at least 20,000 times (i.e., in more than one third of all frames) during the first half of the Sample Game 3. Thicker and darker edges appear more often, with the maxima for both teams above 50,000 times. Players are placed in their average locations. a A single center forward and few edges between wingers indicate stricter positioning. b Four attackers with close average positions and many edges represent a more varied approach.
