EdgeMaps is a new visualization technique that integrates the representation of explicit and implicit data relations. Explicit relations are specific connections between entities already present in a given dataset, while implicit relations are based on the similarity measures derived from shared properties in multidimensional data. EdgeMaps combine spatialization and graph drawing techniques to visualize both types of relations. By activating only one node at a time and distinguishing between incoming and outgoing edges, interesting visual patterns emerge resembling fireworks and waves.
