Coordinating overviews and detail views of WWW log data

Web server log analysis tools provide site operators with useful information regarding the visitors to their sites.� Unfortunately, the utility of these tools is often limited by the use of aggregate summaries that hide the information associated with individual requests, and by the absence of contextual data that might help users interpret those summaries. Building upon earlier work in the use of starfield visualizations to display web site requests as individual data points [8], this paper describes the use of multiple-coordinated visualizations of web log data at varying granularities, and alongside additional related displays of appropriate contextual information.
