Representing vast amounts of information on our relatively small screens is becoming increasingly problematic and has been associated with difficulties in information navigation and interpretation. User interface research has proposed several approaches to address these problems. These methods create displays that vary considerably, visually and algorithmically. I will present a unified geometric framework that provides a way of relating these seemingly distinct methods, facilitating the inclusion of more than one presentation method in a single interface. Furthermore, it supports extrapolation between the methods it describes. Of particular interest are the presentation possibilities that exist in the ranges between fisheye views and Perspective Wall, between magnified insets and detail-in-context, and between detail-in-context presentations and a full-zooming environment. From this unified framework we have created a presentation library in which geometric layout variations are available independently from the mode of graphic representation. The intention is to promote the ease of exploration and experimentation into the use of varied presentation combinations.
