A useful starting point for designing advanced graphical user interjaces is the Visual lnformation-Seeking Mantra: overview first, zoom and filter, then details on demand. But this is only a starting point in trying to understand the rich and varied set of information visualizations that have been proposed in recent years. This paper offers a task by data type taxonomy with seven data types (one-, two-, three-dimensional datu, temporal and multi-dimensional data, and tree and network data) and seven tasks (overview, Zoom, filter, details-on-demand, relate, history, and extracts).

north @ cs.umd.edu, ben @ cs.umd.edu Multiple coordinated visualizations enable users to rapidly explore complex information. However, users often need unforeseen combinations of coordinated visualizations that are appropriate for their data. Snap-Together Visualization enables data users to rapidly and dynamically mix and match visualizations and coordinations to construct custom exploration interfaces without programming. Snap's conceptual model is based on the relational database model. Users load relations into visualizations then coordinate them based on the relational joins between them. Users can create different types of coordinations such as: brushing, drill down, overview and detail view, and synchronized scrolling. Visualization developers can make their independent visualizations snap-able with a simple API. Evaluation of Snap revealed benefits, cognitive issues, and usability concerns. Data savvy users were very capable and thrilled to rapidly construct powerful coordinated visualizations. A snapped overview and detail-view coordination improved user performance by 30-80%, depending on task.

Abstract-We survey work on the different uses of graphical mapping and interaction techniques for visual data mining of large data sets represented as table data. Basic terminology related to data mining, data sets, and visualization is introduced. Previous work on information visualization is reviewed in light of different categorizations of techniques and systems. The role of interaction techniques is discussed, in addition to work addressing the question of selecting and evaluating visualization techniques. We review some representative work on the use of information visualization techniques in the context of mining data. This includes both visual data exploration and visually expressing the outcome of specific mining algorithms. We also review recent innovative approaches that attempt to integrate visualization into the DM/KDD process, using it to enhance user interaction and comprehension.

“Words and rocks contain a language that follows a syntax of splits and ruptures. Look at any word long enough and you will see it open up into...a terrain of particles, each containing its own void... ” Robert Smithson (1996) This article presents both theoretical and technical bases on which to build a ‘‘science of text visualization.’’ These conceptually produce ‘‘the ecological approach,’’ which is rooted in ecological and evolutionary psychology. The basic idea is that humans are genetically selected from their species history to perceptually interpret certain informational aspects of natural environments. If information from text documents is visually spatialized in a manner conformal with these predilections, its meaningful interpretation to the user of a text visualization system becomes relatively intuitive and accurate. The SPIRE text visualization system, which images information from free text documents as natural terrains, serves as an example of the ‘‘ecological approach’’ in its visual metaphor, its text analysis, and its spatializing procedures. This article both formalizes Smithson’s evocative prose and responds to Steven Eick’s recent challenge (Eick, l997) to proceed to a real “science of information visualization.” It describes the theoretical rationale and technical basis of

is an environment for creating interactive visualization applications. WEAVE differs from previous systems in that it provides transparent linking between custom 3-D visualizations and multidimensional statistical representations, and provides interactive color brushing betwen all visualizations. In this paper, we demonstrate how WEAVE can be used to rapidly prototype a biomedical application, weaving together simulation data, measurement data, and 3-d anatomical data concerning the propagation of excitation in the heart. These linked statistical and custom three-dimensional visualizations of the heart can allow scientists to more effectively study the correspondance of structure and behavior.

Analyzing and monitoring logs that portray system, user, and network activity is essential to meet the requirements of high security and optimal resource availability. While most systems now possess satisfactory logging facilities, the tools to monitor and interpret such event logs are still in their infancy. This paper describes an approach to relieve system and network administrators from manually scanning sequences of log entries. An experimental system based on unsupervised neural networks and spring layouts to automatically classify events contained in logs is explained, and the use of complementary information visualization techniques to visually present and interactively analyze the results is then discussed. The system we present can be used to analyze past activity as well as to monitor real-time events. We illustrate the system’s use for event logs generated by a firewall, however it can be easily coupled to any source of sequential and structured event logs.

Rivet is a visualization system for the study of complex computer systems. Since computer systems analysis and visualization is an unpredictable and iterative process, a key design goal of Rivet is to support the rapid development of interactive visualizations capable of visualizing large data sets. In this paper, we present Rivet's architecture, focusing on its support for varied data sources, interactivity, composition and user-defined data transformations. We also describe the challenges of implementing this architecture efficiently and flexibly. We conclude with several examples of computer systems visualizations generated within Rivet, including studies of parallel systems, superscalar processors, and mobile network usage. 1

1 An empirical comparison of three commercial information visualization systems on three different databases is presented. The systems use different paradigms for visualizing data. Tasks were selected to be "ecologically relevant", i.e. meaningful and interesting in the respective domains. Users of one system turned out to solve problems significantly faster than users of the other two, while users of another system would supply significantly more correct answers. Reasons for these results and general observations about the studied systems are discussed. 1.

Direct manipulation of visualizations is a powerful technique for performing exploratory data operations such as navigation, aggregation, and filtering. Its immediacy facilitates rapid, incremental, and reversible forays into the data. However it does not provide for reuse or modification of exploration sessions. This paper describes a visual query language, VQE, that adds these capabilities to a direct manipulation exploration environment called Visage. Queries and visualizations are dynamically linked: operations on either one immediately update the other, in contrast to the feedforward sequence of database query followed by visualization of results common in traditional systems. These features are supported by the architectural concept of threads, which represent a sequence of navigation steps on particular objects. Because they are tied to particular data objects, they can be directly manipulated. Because they represent operations, they can be generalized into queries. We expect t...
