We present three novel tools for creating data graphics: (1) SageBrush, for assembling graphics from primitive objects like bars, lines and axes, (2) SageBook, for browsing previously created graphics relevant to current needs, and (3) SAGE, a knowledge-based presentation system that automatically designs graphics and also interprets a user's specifications(More)
This paper describes AutoBrief, an experimental intelligent multimedia presentation system that generates presentations in text and information graphics in the domain of transportation scheduling. Acting as an intelligent assistant, AutoBrief creates a presentation to communicate its analysis of alternative schedules. In addition, the multimedia(More)
In this paper we present a new set of interactive techniques for 2D and 3D visualizations. This set of techniques is called SDM (Selective Dynamic Manipulation). Sele(rive, indicating our goal for providing a high degree of user control in selecting an object set, in selecting interactive techniques and the properties they affect. and in the degree to which(More)
Graphical presentations can be used to communicate information in relational data sets succinctly and effectively. However, novel graphical presentations about numerous attributes and their relationships are often difficult to understand completely until explained. Automatically generated graphical presentations must therefore either be limited to simple,(More)
An important component of adaptable interactive systems is the ability to model the system's users. Previous systems have relied on user models tailored to the particular needs of that system alone. This paper presents the notion of a general user model, and describes some of our research on building a general user modelling facility that could be used by a(More)
Selective Dynamic Manipulation (SDM) is a paradigm for interacting with objects in visualizations, Its methods offer a high degree of selectivity, in choosing object sets, in the selection of interactive techniques and the properties they affect, and in the degree to which a user action affects the visualization, Our goal is to provide a flexible set of(More)
Our approach views data-graphic design as two complementary processes: design as a constructive process of selecting and arranging graphical elements, and design as a process of browsing and customizing previous cases. We present three novel tools for supporting these processes. SageIlrus/z assembles data-graphics from primitive elements like bars, lines,(More)
Currently, there are many hypertext-like tools and database retrieval systems that use keyword search as a means of navigation. While useful for certain tasks, keyword search is insufficient for browsing databases of data-graphics. SageBook is a system that searches among existing data-graphics, so that they can be reused with new data. In order to fulfill(More)
A unification-based approach to visualization design provides a uniform way of representing user requirements , design knowledge, and graphic designs as well as algorithms for synthesizing graphic presentations. We demonstrate this approach on two types of requirements – structural in the form of sketches and functional in the form of tasks. With this(More)
