Hello, We have made the Jigsaw visual analytics system available to anyone for download. The link can be found at http://www.cc.gatech.edu/gvu/ii/jigsaw. Jigsaw may be useful for understanding collections of text documents -- It combines computational text mining techniques with interactive visualizations. The system just requires that you have java on your computer. The website above includes a tutorial document as well as a series of short tutorial videos. The site (and distribution) also includes a number of example document collections in a convenient XML-ish format. One that may be of special interest to this community is a collection of all InfoVis and VAST papers -- not the full papers' text, but the title, abstract, authors, conference, year, and other metadata.
