Abstract

We introduce a variation on TreeMaps called DagMaps that have been adapted to interactively explore hierarchies describing inheritance relations. Inheritance relations occur naturally, for instance, between companies and their subsidiaries. Inheritance relations are also useful for capturing clustering structures with overlapping clusters. In all of these cases, the graph underlying the inheritance relations is a directed acyclic graph (DAG). Inheritance relations are explored using a treemap built from the DAG. Moreover, inheritance can be explored at various levels of detail, turning the combined use of DagMaps with traditional node-link representations of DAGs into a very useful visual and interactive tool. User interaction can vary the level of detail to visually identify multiple inheritances as duplicates in the DagMap and locate common inheritances/genealogies in the tree.
