2004 International Conference on Information Technology: Coding and Computing, 2004. Proceedings. ITCC 2004.  
Our visualization scheme extends recent work in the visualization of large hierarchies with primary focus on algorithmic and visual simplicity.  ...  The scheme also helps user view information associated with nodes and links besides navigating through the network hierarchy.  ...  Efforts have been made to make this space filling technique more effective in visualizing information hierarchy. Treemaps can easily handle hierarchies with tens and thousands of leaf nodes.  ...
