Aim of the Workshop

Information visualization can be defined as the use of computer-supported, interactive, visual representations of abstract data to amplify cognition (Card et al. 1999). The research discipline Information Visualization combines aspects of scientific visualization, human-computer interaction, data mining, imaging and graphics. It focuses on information that is often abstract. This means that information often has no natural and o.bvious representation. A key research problem is to discover adequate visual metaphors for making information more accessible and to understand which analytical tasks they support. The largest information space is perhaps the World Wide Web, which contains millions of pages. Information visualization in this domain enables users to get information quickly, to put it in a meaningful shape, and to make decisions in a relatively short time. Web-based information visualization describes visualization applications that use the Web as an information source, a delivery mechanism for visualization, or both (Rohrer, Swing 1997). The aim of this workshop is to bring together researchers and pract1t10ners who are working in key technology areas of information visualization in order to discuss recent research findings and address complementary research and development issues. Of particular interest are contributions describing different visualization techniques to make use of the information available on the Web or how to harnes
