Graph Folding: Extending Detail and Context Viewing into a Tool for Subgraph Comparisons
It is a di cult problem to display large, complex graphs in a manner which furthers comprehension. A useful approach is to expand selected sections foci of the graph revealing details of subgraphs. If this expansion is maintained within the context of the entire graph, information is provided about how subgraphs are embedded in the overall structure.Often it is also desirable to realign these foci in order to facilitate the visual comparison of subgraphs. We have introduced a distortion-based viewing tool, three-dimensional pliable surface 3DPS 1 , which allows for multiple arbitrarily-shaped foci on a surface that can be manipulated by the viewer to control the level of detail contained within each region. This paper extends 3DPS to include the repositioning of foci so as to bring together spatially separated regions for the purpose of comparison while retaining the e ect of detail in context viewing. The signi cance of this approach is that it utilizes precognitive perceptual cue...
