To appear in Neurocomputing Special Issue Visual Analytics using Multidimensional Projections , 2014. Our analysis resulted in three design guidelines: 1 the number of levels in display and data should match; 2 high visual levels should only display task-relevant information; 3 simultaneous display, rather than temporal switching, is suitable for tasks with multi-level answers. Quick search: within: Synthesis Lectures on Visualization Editor , Purdue University, University of Maryland Synthesis Lectures on Visualization publishes 50- to 100-page publications on topics pertaining to scientific visualization, information visualization, and visual analytics. Accordion drawing for comparing gene sequences. Design study about a visualization tool that supports exploration of multiple possible computational summaries that mix spatial information about each cell in a developing fruit fly embryo, gene expression measurements over time, and data from multiple related species or organisms.

We describe the data information display needs of immunologists and describe the design decisions used to create Cerebral, a system that incorporates experimental data directly into the graph display, using the biologically guided graph layout announced in the. Lam's current research interests include understanding how visualization can be used to support exploratory data analysis. We demonstrate its benefits in a detailed comparison against several previous algorithms. Earlier she was a technical staff member at the National Science Foundation Research Center for Computation and Visualization of Geometric Structures The Geometry Center at the University of Minnesota from 1991 to 1995. Glint is designed to automatically minimize the total number of distances computed by progressively computing a more and more densely sampled approximation of the distance matrix. To facilitate discussion, we cast our analysis findings into a four-point decision tree: 1 When are multi-level displays useful? The system generates hierarchies that reflect the underlying graph topology by requiring that subgraphs respect edge and connectivity conservation.
Dagstuhl Follow-Ups 2, 2011, Chapter 17, p 240--259. Limitations of Study Design Recommendations Discussion and Future Work. To shed more light on this complex topic, we conducted a systematic review of 22 existing multi-level interface studies to extract high-level design guidelines. Visualization and Computer Graphics Proc. These proceedings were also published as Rendering Techniques 2000, B. To shed more light on this complex topic, we conducted a systematic review of 22 existing multi-level interface studies to extract high-level design guidelines.

An extension to the four-level for design and validation of visualization systems that defines the term guidelines in terms of blocks at each level. Contextual note: this post is one of several.
For the task we studied, point-based spatializations were far superior to landscapes, and 2D landscapes were superior to 3D landscapes. Visualization and Computer Graphics Proc. The book features a unified approach encompassing information visualization techniques for abstract data, scientific visualization techniques for spatial data, and visual analytics techniques for interweaving data transformation and analysis with interactive visual exploration. Visualization and Computer Graphics 16 6 :908-917 Proc. Proceedings of , Montreal, Canada, August 1998, Lecture Notes in Computer Science 1547, pp.
Our goal is to evaluate the progress of the maturing field of visualization, to help focus and direct future research projects, and to provide guidance on how to apportion national resources. We considered three multi-level interface types in this synthesis review: temporal, or temporal switching of the different levels as in zooming interfaces; separate, or displaying the different levels simultaneously but in separate windows as in overview + detail interfaces; and embedded, or showing the different levels in a unified view as in focus + context interfaces. The E-mail message field is required. Our findings and recommendations reflect not only information gathered from visualization and applications scientists during two workshops on Visualization Research Challenges but also input from the larger visualization community. Visualization Analysis and Design provides a systematic, comprehensive framework for thinking about visualization in terms of principles and design choices. A paper on interactive rendering of scenes where objects can have different projections, as in the simulaneous multiple viewpoints of Cubist paintings.
It does not assume any previous experience in programming, mathematics, human-computer interaction, or graphic design and can be used in an introductory visualization course at the graduate or undergraduate level. Very large graphs can be navigated at a constant frame rate, as long as the entire graph can fit into main memory. An article which briefly reviews the H3 layout and H3Viewer drawing algorithms. Stasko, Jean-Daniel Fekete, Chris North, eds. She received a PhD from the University of British Columbia in 2008, studying with Dr. A paper that presents a much improved layout algorithm that exploits some of the properties of 3D hyperbolic space to achieve reasonable information density. The paper page includes my current list of favorite design study examples.
She has worked on visualization projects in a broad range of application domains, including evolutionary biology, genomics, systems biology, large-scale system administration, computer networking, web log analysis, computational linguistics, and geometric topology.
