Performance visualization: 2-D, 3-D, and beyond

During the past ten years, performance data visualization techniques have evolved from static, two-dimensional graphics to dynamic graphics and immersive virtual environments. We sketch the domain of applicability for each visualization technique using analysis of input/output behavior and WWW traffic as example problem domains. With this background, we describe experiences with virtual environment representations of complex performance data and the potential for immersive interaction with complex software.
