WWW95: visualizing the Web with the navigational view builder
overview diagrams are one of the best tools for orientation and navigation in
hypermedia systems. however, constructing effective overview diagrams is a
challenging task. this paper describes the Navigational View Builder, a tool
which allows the user to interactively create useful visualizations of the

sougata mukherjea from the
college of computing of the
georgia institute of technology
atlanta, USA showed how difficult it is to create a graphical overview
of the information space. he explained the four strategies they use to
form effective views:
- binding (bind attributes to visual properties, e.g. colors)
- clustering (combine multiple documents into one graphical object)
- filtering (display only documents that are of interest to the user)
- hierarchization (create a visual hierarchy)
it is obvious that a large information space cannot be displayed with
traditional diagrams using nodes to represent documents and lines to
represent links, because the picture gets cluttered with boxes and lines and
becomes completely useless. if one or more of the above mentioned strategies
are applied to the diagram, the amount of information can be reduced and
more useful pictures will result. such graphical representations of the
information space allow fast and efficient navigation.
the only trouble with that system is, the properties of the HTML documents
are not stored in the document itself, but they have to be entered manually.
therefore the view of the information space presented by the navigational
view builder may not be up to date. nevertheless i liked the various
graphical presentations of the information space. once the information
about the links and the properties of the documents is stored in a database,
such visualization tools might become even more important and useful.

available on the Web.
