Two dimensional visualization of a state transition graph with 191 states. networks [8]. Since finding a general solution for visualizing large directed graphs can be difficult, most existing methods are forced to use domain specific information. In this case, we focus on large state transition graphs, which are automatically generated from high level process descriptions and ....

....resulting visualizations are mostly static. Narcissus is the name of a sophisticated visualization tool for web pages that uses self organizing systems and a modified version of XMosaic to generate three dimensional information spaces of active objects that a user can navigate and manipulate [14]. All active objects follow the same set of task dependent rules: they exert a repulsive force on all of the other objects and they attract objects that are related. Users determine by hand which relationships are active within the model, thus influencing the final layout. Running the model, the ....

This type of self organising structure, based on the spring mass metaphor, occurs in several systems such as Hyperspace s successor Narcissus [15], and others [16; 17; 18; 19] The effect of this clustering is analogous to the concept of chunking in drop down menus.

....nodes in the system exert repulsive force on the others and related nodes are attracted to each other. After several iterations in which the positions are adjusted according to the calculated force, the system stabilizes, yielding clusters which are visually apparent. In a case study of Narcissus[60], the authors report that this technique can produce useful clusters in a relatively small number of iterations. As with other N body problems, the complexity is O(N 3 ) Another example of clustering by layout is described for the SemNet system[42] where clustering is accomplished by using ....

....SemNet[42] is one of the few systems to provide graph editing while still providing a comprehensive set of tools to visualize large graphs. It is also one of the earliest complete systems that we know about. Clustering has been applied by many older systems such as SemNet[42] Narcissus[60], SKETCH[118] and the Navigational View Builder[91] Some newer systems that cluster graphs are NicheWorks[126] DA TU[70] STARLIGHT[105] and a system used by Bell Laboratories[58] for network visualization. NicheWorks is an example of a complete system implementation that can be adapted for ....

....very synthetic since tens or hundreds of computers could be represented on the screen, while in the second VIRTUAL REALITY AND PROTOTYPING June 1999, Laval (France) case the representation should be very detailed since the user only requires information about that specific workstation. Clustering [12] is one way to do so, the use of different levels of detail [13] is another one. Clustering consists in replacing several glyphs with a new glyph that is a synthetic representation of all the information contained in the hidden glyphs. Complex 3D glyphs that display a lot of information may be ....

....children) 4.3.3 Managing dynamics It should be noted that data dynamic, which has been discussed for the structuring layer, has also an impact on the presentation layer. Any modification in the service model must be presented to the user and the virtual world should be modified accordingly [24]. In particular, if the number or dimension of the components managed by a layout manager change substantially, this layout manager must recompute the new position and orientation of those components. It may also have to propagate the changes to its parent (if existing) and to its other children. ....

These techniques do not produce a single snapshot of a document base; rather, they provide views that can be manipulated to best meet a user s needs or perspective. Some visualization schemes are particularly well suited to certain types of data. Within the Xerox PARC s Information Visualizer ....

.... suggest that the whole visualization not be reworked based on small additions, but that instead topological consistency should be preserved (Lueders and Ernst, 1995) In the Narcissus visualizer, each document has a behavior that repels it from some objects while attracting it to others (Hendley, 1995). With a dynamic corpus in Narcissus, the user could watch the visualization self organize into a different layout, providing feedback concerning the changes brought on by yesterday s news, for example. Our first attempts at whole corpus visualizations will likely preserve views of the data at ....

The NZDL contains several other smaller collections, such as the 500 volume Gutenberg collection of English literature, a collection comprising all Internet FAQ lists, and so on. HyperSpace is a general purpose visualisation tool based on Narcissus (Drew et al. 1995) which uses a representation of 3D space to generate images of data. There are two forms of basic representation within the space: nodes and links. Nodes are spherical objects; links join nodes. Each of these basic types has a defined behaviour, which allows the structures produced to organise ....
