Static and dynamic evolution of software systems may be described in terms of
connection additions and removals in a graph. Due to the inherent complexity of
software, navigating through such a dynamic network is a non-trivial task and
extracting relevant information typically involves sophisticated queries. We
explore the notion of space-time cube, a well-known 3D representation of an
evolving dynamic graph, to support a set of software engineering activities.
CuboidMatrix is a visualization tool that offers simple and expressive
navigation operations. We have evaluated our tool against two software
comprehension activities, namely (i) assessing interaction of classes during a
software execution and (ii) exploring the cause of breaking Lint-like quality
rules over a large number of software revisions.
