This is the Graph visualizer for the Tournament Allocation Problem. Nodes represent players while edges are the conflicts between them. A conflict is any kind of
undesired interaction in a tournament structure. For this specific instance, conflicts are matches between the same pair of players in the first round (+5), second round (+2), third round (+1), quarter and semi final rounds (+0.5)
and players from the same country (+5). Node size is proportional to weighted degree, edges to their weights.
