ABSTRACT
This paper describes major concepts of a scalable information visualization framework. We assume that the exploration of heterogeneous information spaces at arbitrary levels of detail requires a suitable preprocessing of information quantities, the combination of different graphical interfaces and the illustration of the frame of reference of given information sets. The innovative features of our system include dynamic hierarchy computation and user controlled refinement of those hierarchies for preprocessing unstructured information spaces, a new Focus+Context technique for visualizing complex hierarchy graphs, a new paradigm for visualizing information structures within their frame of reference and a new graphical interface that utilizes textual similarities to arrange objects of high dimensional information space in 3-dimensional visualization space.

Information visualization using a new focus+context technique in combination with dynamic clustering of information space
NPIVM '99: Proceedings of the 1999 workshop on new paradigms in information visualization and manipulation in conjunction with the eighth ACM internation conference on Information and knowledge managementThis paper presents work in progress on our approach to visualizing multi-dimensional and hierarchical information. We propose two new graphical user interfaces, the Magic Eye View (MEV) and ShapeVis to explore information spaces. In order to cope with ...
Polyarchy visualization: visualizing multiple intersecting hierarchies
CHI '02: Proceedings of the SIGCHI Conference on Human Factors in Computing SystemsWe describe a new information structure composed of multiple intersecting hierarchies, which we call Polyarchies. Visualizing polyarchies enables use of novel views for discovery of relationships which are very difficult using existing hierarchy ...
