Welcome to OLIVE, the On-line Library of Information Visualization Environments! Listed to the left are eight categories of information visualization environments differentiated by data type. Within each category we have gathered what we feel are the most important citations, commercial products, research projects, and videos. This web-site is a class project for Dr. Ben Shneiderman's fall 1997 CMSC 828/838S graduate course on Information Visualization at the University of Maryland, College Park, Department of Computer Science.
Dr. Shneiderman originally proposed a taxonomy of information visualization environments in his paper, The eyes have it: A task by data type taxonomy of information visualizations (A Text Only version is available as well). Following this taxonomy, Chris North assembled a reference set which he titled, A Taxonomy of Information Visualization User-Interfaces. Building on that original reference set, and Dr. Shneiderman's recent book, Designing the User Interface (3rd Edition), our class has attempted to update, expand, and annotate Chris North's original page.
Modern visual environments often go much further than just viewing static data -- dynamic and flexible user control are becoming more of a reality, and possibly a necessity. The day of text-based interfaces and lists of data may be fading. Though each group has attempted to outline both the positives and negatives of the environments they found, one useful general criteria suggests itself when evaluating all the environments. Dr. Shneiderman's mantra, "Overview first, zoom and filter, then details on demand," provides an excellent framework which can apply to all environments. By applying such concepts, we can proceed on the journey to environments that empower users to deal with more complex data and tasks.
We provide several approaches to viewing our site with the idea of illustrating a few of the approaches available for visualizing information presented on the web. Specifically, we offer a traditional Graphics & Text interface, a Frames interface, a Text Only interface, and a WebTOC interface. To avoid duplicate data that can become inconsistent between interfaces, we dynamically rebuild the entire web-site whenever changes are made to the input files for the site. A detailed report on this process is available at: http://otal.umd.edu/Olive/Report.html.
