Past, present, and future in and of software visualization

Starting with a selective retrospective of the history of software visualization, I will identify various trends and paradigms of previous and current research. In particular, I will discuss examples of applying visualization techniques to analyze the past and present state of software as well as to predict its future development. I will argue that prediction is an important task, but that software visualization research has only scratched the surface of it. As a consequence, speculative visualization will be one of the major future challenges identified in this talk.
