Analyzing large-scale software systems is a costly process in the absence of dedicated tools. Using visualization techniques, humans are able to quickly assess large amounts of information and detect patterns. In this talk we present CodeCity, a 3D visualization tool revolving around a city metaphor, for building interactive visualizations of large object-oriented software systems. We extended our approach to allow the visual exploration of evolving software systems and the localization of design problems.

CodeCity features a domain-specific scripting language, allowing the users to define custom visualizations. Written in VisualWorks Smalltalk, CodeCity is capable of visualizing software systems written in Java, Smalltalk, and C++.
