Abstract:
This paper describes a new information
visualization technique for web site mapping. It can
be used especially for the display of very large web
sites in a 2-dimensional space. Our strategy is to
optimize the drawing of trees in a geometrical plane
and maximize the utilization of display space by
allowing more nodes and links to be displayed at a
limit screen resolution. To enable the exploration of
large web site-maps, we use a modified semantic
zooming technique to view the detail of a particular
part of the hierarchy at a time based on user's
interest. Layout animation is also provided to
preserve the mental map while the user is exploring
the hierarchy by changing zoomed views.
