Abstract:
Graph layout techniques have been
developed for many years, there is a few
applying to real world applications. This paper
presents an application of applying graph layout
techniques in web information visualization and
navigation. Most Web browsers, including
Netscape and Microsoft Internet Explorer,
cannot give users a visual “map” to guide their
Web journey. An approach of using a graph for
Web navigation has been proposed. That is to
look at the whole of cyberspace as one huge
graph. To explore this huge graph, it is critical to
find an effective method of tracking a sequence
of subsets (Web sub-graphs) of the huge graph
based on the user's focus. Any on-line Web subgraph
should fit in the display window. To
enhance the display of a Web sub-graph, there
should not be any overlaps between node images
in the Web sub-graph.
