Graph-Centric Tools for Understanding the Evolution and Relationships of Software Structures

We present a suite of small tools, implemented as a pipeline of text file manipulating scripts, that, on one hand, measure the evolution of any software structure that can be represented as a directed graph of software elements and relations and, on the other hand, visualise any three attributes of any set of software artefacts that can be related to the elements shown in the graph. We illustrate the applicability of the tool with our work on the evolution of the Eclipse architecture and the relation between bugs and components.
