A Visualization Model for Web Sitemaps

This paper describes a space-efficient visualization model that automatically crawls through a Web site and visualizes its sitemap. This model can be used especially for displaying and navigating a very large Web site in a two-dimensional (2D) plane and/or a three-dimensional (3D) space. The 2D visualization employs EncCon layout algorithm to effectively visualize a very large number of pages and relations at once in which it utilizes the space to display more information. This technique also employs a focus+context navigation method to enable the exploration of large sites. Animation is provided to preserve the user´s mental map while exploring the Web site hierarchy. The 3D visualization extends the 2D EncCon layout algorithm to a three-dimensional space which aims to provide a more realistic look and feel of the information
