Placing numerous data objects and their corresponding labels in limited screen space is a challenging problem in information visualization systems. Extending map-oriented techniques, this paper describes static placement algorithms and develops metrics (such as compactness and labeling rate) as a basis for comparison among these algorithms. A control panel facilitates user customization by showing the metrics for alternative algorithms. Dynamic placement techniques that go beyond map-oriented techniques demonstrate additional possibilities. User actions can lead to selective display of data objects and their labels.

The way in which designers choose between alternatives in user interface design can affect both the design process and also the quality of the outcome, i.e., the user interface. However, little is known about the knowledge drawn on during. or the processes that guide, the choice between design alternatives. This paper presents the results of an empirical study aimed at modelling 'trade-off decision making' in user interface design. It is argued that a single abstract vocabulary can capture important aspects of the rich knowledge drawn on during design problem solving. It is also argued that designers' reasoning during 'choice episodes' is not sophisticated. In choosing between alternatives in design, designers invariably limit the range, or nature, of the alternatives considered. The implications of this finding are discussed.

A dynamic query interface (DQI) is a database access mechanism that provides continuous real-time feedback to the user during query formulation. Previous work shows that DQIs are elegant and powerful interfaces to small databases. Unfortunately, when applied to large databases, previous DQI algorithms slow to a crawl. We present a new incremental approach to DQI algorithms and display updates that work well with large databases, both in theory and in practice.
