Dependence cluster visualization
Syed S. Islam, Jens Krinke, David Binkley · 2010
Large clusters of mutual dependence have long been regarded as a problem impeding comprehension, testing, maintenance, and reverse engineering. An effective visualization can aid an engineer in addressing the presence of large clusters. Such a visualization is presented. It allows a program's dependence clusters to be considered from an abstract high level down thru a concrete source-level. At the highest level of abstraction, the visualization uses a heat-map (a color scheme) to efficiently overview the clusters found in an entire system. Other levels include three source code views that allow a user to "zoom" in on the clusters starting from the high-level system view, down through a file view, and then onto the actual source code where each cluster can be studied in detail.
