Overlapper is a visual analytics tool that incorporates different visualization techniques, besides the core force-directed graph, such as: scatterplot, parallel coordinates, treemap and tag cloud. The tool focus is in very connected groups of people and their overlapping between different social networks (such as movies). Overlapper was developed using a modified force-directed graph representing people as nodes, where all the people involved in a particular movie are joint together in a kind of bubble. Since the tool allows several movies to be mapped in the same space, the resulting environment is a large set of bubbles interconnected by people involved in more than one movie.
