Software Visualization is the field of Software Engineering that aims to help people to understand software through the use of visual resources. It can be effectively used to analyze and understand the large amount of data produced during software evolution. Several Software Evolution Visualization (SEV) approaches have been proposed. The goals of the proposed approaches are varied, and they try to help programmers and managers to deal with software evolution in their daily software activities. Despite their goals, their applicability in real development scenarios is questionable. In this chapter, the authors discuss the current state of the art and challenges in software evolution visualization, presenting issues and problems related to the area, and they propose some solutions and recommendations to circumvent them. Finally, the authors discuss some research directions for the SEV domain.
