RINGS: A Technique for Visualization of Large Hierarchies


We present RINGS, a technique for visualizing large trees. We introduce a new ringed circular layout of nodes to make more efficient use of limited display space. RINGS provides the user with the means to specify areas of primary and secondary focus, and is able to show multiple foci without compromising understanding of the graph. The strength of RINGS is its ability to show more area in focus and more contextual information than existing techniques. We demonstrate the effectiveness of RINGS by applying it to the visualization of a Unix file directory.
