Design Pattern Visualization for Program Comprehension In recent years the usage of design patterns is gaining interest in the software design community. Design patterns provide successful and proven solutions for design problems and common terminologies that are based on the expertise of domain experts, thus providing guidance for both design and comprehension of large-scale software systems. In this presentation we focus on the visualization of design patterns that were recovered from existing source code. In particular we discuss three popular approaches in graph drawing and their applicability to visualize patterns since generating layouts for design patterns can be seen as a graph-drawing problem. The presentation will conclude with some discussion on open problems and some potential future directions to address the challenges of visualizing design patterns
