Website

• Website representation

  • Website presented as directed graph; pages as nodes, links as edges
  • Page type (HTML, GIF, etc) color-coded.
  • Nodes labelled with nickname generated from URL

• Automatic 2D layout of website topology, using enhanced force-directed algorithm.

• Customization:

  • Usability Engineer (UE) can adjust the underlying force model that determines global layout.
  • UE can drag and fix location of specific nodes.

• Simplification:

  • UE can delete nodes of a given type (e.g. mailto: nodes).
  • UE can delete nodes not near to any subject's path.
  • UE can impose a tree structure on the directed graph.

• Other node operations

  • UE can mark/unmark a selected node.
  • UE can view the WWW page of a node.

• UE can re-organize layout according to connection by subject path, rather than static links.
