Abstract:

A fisheye camera lens is a very wide angle lens that magnifies nearby objects while shrinking distant objects. It is a valuable tool for seeing both "local detail" and "global context" simultaneously. This paper describes a system for viewing and browsing graphs using a software analog of a fisheye lens. We first show how to implement such a view using solely geometric transformations. We then describe a more general transformation that allows hierarchical or structured information about the graph to affect the view. Our general transformation is a fundamental extension to previous research in fisheye views.
