ABSTRACT
In this paper a novel approach is described for tree visualization using nested circles. The brother nodes at the same level are represented by externally tangent circles; the tree nodes at different levels are displayed by using 2D nested circles or 3D nested cylinders. A new layout algorithm for tree structure is described. It provides a good overview for large data sets. It is easy to see all the branches and leaves of the tree. The new method has been applied to the visualization of file systems.

A comparative evaluation on tree visualization methods for hierarchical structures with large fan-outs
CHI '10: Proceedings of the SIGCHI Conference on Human Factors in Computing SystemsHierarchical structures with large fan-outs are hard to browse and understand. In the conventional node-link tree visualization, the screen quickly becomes overcrowded as users open nodes that have too many child nodes to fit in one screen. To address ...
Botanical Visualization of Huge Hierarchies
INFOVIS '01: Proceedings of the IEEE Symposium on Information Visualization 2001 (INFOVIS'01)A new method for the visualization of huge hierarchical data structures is presented. The method is based on the observation that we can easily see the branches, leaves and their arrangement in a botanical tree, despite of the large number of elements. ...
Bubble trees the visualization of hierarchical information structures
CHI EA '00: CHI '00 Extended Abstracts on Human Factors in Computing SystemsA tree visualization mechanism is proposed, based on the natural property of trees to recursively sub-categorize themselves into sub-trees. Each sub-tree is graphically represented as a bubble, which aggregates detail by enclosing lower-level ...
