There was a download of VisTrails 2.2.4 on the developer's website when we last checked. We cannot confirm if there is a free download of this software available. The program's installer file is commonly found as python.exe. This free program is a product of Vistrrails. The following versions: 2.2, 2.0 and 1.6 are the most frequently downloaded ones by the program users. VisTrails lies within Education Tools, more precisely Science Tools. We recommend checking the downloaded files with any free antivirus.
From the developer:
VisTrails is an open-source scientific workflow and provenance management system that provides support for simulations, data exploration, and visualization. Whereas workflows have been traditionally used to automate repetitive tasks, for applications that are exploratory in nature, such as simulations, data analysis, and visualization, very little is repeated---change is the norm.
You may want to check out more software, such as Adding Machine, BG Road Maps or Avenue PC, which might be similar to VisTrails.
