System and method for visualizing massive multi-digraphs

摘要

In accordance with a feature of the invention, a hierarchy of multi-digraph layers may be constructed on top of an input multi-digraph. Each layer represents a multi-digraph obtained from an equivalence relation defined on the edge set of the input multi-digraph. In accordance with a further feature of the invention, each subgraph is small enough to be represented visually in a variety of novel ways.
