DocuViz visualizes how a document evolves in Google Docs, showing who did what when. It is a picture of the revision history over time.

Sign in with Google to access the files you would like to visualize.  Select the file and, after a short wait, you can see the visualization.  You can interact with it in several ways and save it.

DocuViz was developed by the Hana Lab at UC Irvine, including Dakuo Wang, Jingwen Zhang, Judy Olson, Gary Olson, and Trung Nguyen.
