Using Space-Optimized Tree Visualizaton for Web Site-Mapping.
Quang Vinh Nguyễn, Mao Lin Huang · International Conference on Internet Computing · 2002
This paper describes a new information visualization technique for web site mapping. It can be used especially for the display of very large web sites in a 2-dimensional space. Our strategy is to optimize the drawing of trees in a geometrical plane and maximize the utilization of display space by allowing more nodes and links to be displayed at a limit screen resolution. To enable the exploration of large web site-maps, we use a modified semantic zooming technique to view the detail of a particular part of the hierarchy at a time based on user's interest. Layout animation is also provided to preserve the mental map while the user is exploring the hierarchy by changing zoomed views.
