The demand for the construction of complex visualizations is growing in many disciplines of science, as users are faced with ever increasing volumes of data to analyze. The authors present VisTrails, an open-source provenance management system that provides infrastructure for data exploration and visualization.
The article describes a set of visualizations on a structured volume obtained from a CT scan of a head. The first visualization is produced with a script and all subsequent visualizations take advantage of the visual programming interface provided by VisTrails. The running example in the text starts with basic isosurfacing and plotting, then moves to volume rendering, slicing, and interactive visualizations with user controlled interaction widgets.
