Visualizing the Evolution of Software Systems Using the Forest Metaphor
Ugo Erra, Giuseppe Scanniello, Nicola Capece · 2012 16th International Conference on Information Visualisation · 2012
We present an approach based on a forest metaphor to ease the comprehension of evolving object oriented software systems. The approach takes advantages of familiar concepts such as forests of trees, sub-forest of trees, trunks, branches, leaves, and color of the leaves. In particular, each release of a software is represented as a forest that users (or software maintainers) can navigate and interact with. Users can pass from a release to another one, so understanding how the entire software and its classes evolve throughout the past releases. The approach has been implemented in a prototype of a 3D interactive environment. A preliminary empirical evaluation has been also conducted to assess that environment and the underlying approach.
