HGV: A library for hierarchies, graphs, and views. We introduce the base architecture of a software library which combines graphs, hierarchies, and views and describes the interactions between them. Each graph may have arbitrarily many hierarchies and each hierarchy may have arbitrarily many views. Both the hierarchies and the views can be added and removed dynamically from the corresponding graph and hierarchy, respectively. The software library shall serve as a platform for algorithms and data structures on hierarchically structured graphs. Such graphs become increasingly important and occur in special applications, e.g., call graphs in software engineering or biochemical pathways, with a particular need to manipulate and draw graphs.

This software is also peer reviewed by journal TOMS.
