This picture shows the superheroes of Marvel movies (such as the Avengers and Captain America). The layout employs a Voronoi treemap approach. Each Marvel movie character is represented by a circular node, and each movie is represented by a base Voronoi cell. Higher-level Voronoi cells represent the various series of Marvel movies.
One can see the importance of the Avengers movie series, consisting of four movies, coloured with variants of wine colour. The important Captain America movie series, consisting of three movies, is coloured with variants of blue.
