Hyperbolic Trees

Browsing a large hierarchy, like an organization chart or a directory structure, is difficult, because the hierarchies typically grow exponentially. Such exponentially growing structures don't fit well in the Euclidean plane, or even in Euclidean 3-space.

But we can pick a better geometry. Hyperbolic geometry affords an exponentially growing space, so we lay out a hierarchy in the hyperbolic plane. Then we use the Poincare model to provide a fisheye view on a display, as shown in the picture. The user can focus on whatever part interests them while seeing a context of the entire hierarchy.

Visualizing the Structure of the World Wide Web in 3D Hyperbolic Space (The Geometry Center. University of Minnesota)

Abstract: We visualize the structure of sections of the World Wide Web by constructing graphical representations in 3D hyperbolic space. The felicitous property that hyperbolic space has ``more room'' than Euclidean space allows more information to be seen amid less clutter, and motion by hyperbolic isometries provides for mathematically elegant navigation. The 3D graphical representations, available in the WebOOGL or VRML file formats, contain link anchors which point to the original pages on the Web itself. We use the Geomview/WebOOGL 3D Web browser as an interface between the 3D representation and the actual documents on the Web. The Web is just one example of a hierarchical tree structure with links ``back up the tree'' i.e. a directed graph which contains cycles. Our information visualization techniques are appropriate for other types of directed graphs with cycles, such as filesystems
with symbolic links.
