There have been two types of Web visualization techniques: visualization of Web sites themselves based on such as link structures or lexical contents, and visualization of browsers’ behaviors. We think that integration of such two visualization techniques is very useful for Web site management, and therefore we are currently studying on visualization of access pattern and link structure on a single screen. This paper presents a Web visualization technique using our own multiple-category-embedded graph visualization technique. The presented technique constructs link structures using crawler software, and access patterns from access log files. It then integrates them and visualizes by our graph visualization technique. We expect that users can visually understand the relationship between access patterns and link structures, and utilize the knowledge for design and management of Web sites. This paper shows our case study and discusses typical access patterns we observed by the techniq...
