Hello, and welcome to the VisTrails Wiki.

What is it?

VisTrails is a new system that enables interactive multiple-view visualizations by simplifying the creation and maintenance of visualization pipelines, and by optimizing their execution. It provides a general infrastructure that can be combined with existing visualization systems and libraries.

By maintaining the provenance of both the visualization processes and data they manipulate, it enables reproducibility and simplifies the complex problem of creating and maintaining visualization products. This allows scientists to efficiently and effectively explore data through visualization: they can explore their visualization product by returning to previous versions of a dataflow (or visualization pipeline), apply a dataflow instance to different data, explore the parameter space of the dataflow, query the visualization history, and comparatively visualize different results.

Please note that some of these videos were generated using versions of VisTrails, and the interface might look different than the one available in the most up-to-date version.

	Demonstration This video shows basic usage of VisTrails by going through three examples. Some of the features shown are: Manipulating a pipeline by adding modules and connections and setting parameters Performing a parameter exploration As this is an old version of the system, some of the features are not currently available. High Resolution(81 MB) Medium Resolution(29 MB) Low Resolution(16 MB)
	Radiation Oncology This video shows how some of VisTrails features were used on a Radiation Oncology study. As this is an old version of the system, some of the features are not currently available. High Resolution(70 MB)
