Abstract
This paper presents a tool for visualizing Web access logs, which has two views. The left view represents Web sitemaps by a set of webpage icons. It places the icons onto display spaces by data jewelry box algorithm. The right view represents Web access statistics by a bar chart. It aggregates the accesses according to user-specified attributes, such as time, client, and status. When a user clicks a bar in the right view, the left view highlights icons that have corresponding accesses. When a user clicks an icon in the left view, the right view shows the access statistics of the clicked webpage. These combinations of the two views help users to find problems of websites, and discover trends of accesses.
