Adaptive Privacy-Preserving Visualization Using Parallel Coordinates
Found in: IEEE Transactions on Visualization and Computer Graphics
By Aritra Dasgupta,Robert Kosara
Issue Date:December 2011
pp. 2241-2248
Current information visualization techniques assume unrestricted access to data. However, privacy protection is a key issue for a lot of real-world data analyses. Corporate data, medical records, etc. are rich in analytical value but cannot be shared witho...
Laws of Attraction: From Perceptual Forces to Conceptual Similarity
Found in: IEEE Transactions on Visualization and Computer Graphics
By Caroline Ziemkiewicz, Robert Kosara
Issue Date:November 2010
pp. 1009-1016
Many of the pressing questions in information visualization deal with how exactly a user reads a collection of visual marks as information about relationships between entities. Previous research has suggested that people see parts of a visualization as obj...
Pargnostics: Screen-Space Metrics for Parallel Coordinates
Found in: IEEE Transactions on Visualization and Computer Graphics
By Aritra Dasgupta, Robert Kosara
Issue Date:November 2010
pp. 1017-1026
Interactive visualization requires the translation of data into a screen space of limited resolution. While currently ignored by most visualization models, this translation entails a loss of information and the introduction of a number of artifacts that ca...
The Shaping of Information by Visual Metaphors
Found in: IEEE Transactions on Visualization and Computer Graphics
By Caroline Ziemkiewicz, Robert Kosara
Issue Date:November 2008
pp. 1269-1276
The nature of an information visualization can be considered to lie in the visual metaphors it uses to structure information. The process of understanding a visualization therefore involves an interaction between these external visual metaphors and the use...
Storytelling: The Next Step for Visualization
Found in: Computer
By Robert Kosara,Jock Mackinlay
Issue Date:May 2013
pp. 44-50
Presentation—specifically, its use of elements from storytelling—is the next logical step in visualization research and should be a focus of at least equal importance with exploration and analysis.
Visualization Criticism
Found in: IEEE Computer Graphics and Applications
By Robert Kosara, Fritz Drury, Lars Erik Holmquist, David H. Laidlaw
Issue Date:May 2008
pp. 13-15
Criticism of designs and ideas is an important tool in art and design—and it can also be used to great effect in visualization teaching and research. We describe the basics of critiquing in visual art, where the goal is to teach the students to see and to ...
WireVis: Visualization of Categorical, Time-Varying Data From Financial Transactions
Found in: Symposium On Visual Analytics Science And Technology
By Remco Chang, Mohammad Ghoniem, Robert Kosara, William Ribarsky, Jing Yang, Evan Suma, Caroline Ziemkiewicz, Daniel Kern, Agus Sudjianto
Issue Date:November 2007
pp. 155-162
Large financial institutions such as Bank of America handle hundreds of thousands of wire transactions per day. Although most transactions are legitimate, these institutions have legal and financial obligations in discovering those that are suspicious. Wit...
Visualization Criticism - The Missing Link Between Information Visualization and Art
Found in: Information Visualisation, International Conference on
By Robert Kosara
Issue Date:July 2007
pp. 631-636
Classifications of visualization are often based on technical criteria, and leave out artistic ways of visualizing information. Understanding the differences between information visualization and other forms of visual communication provides important insig...
Parallel Sets: Interactive Exploration and Visual Analysis of Categorical Data
Found in: IEEE Transactions on Visualization and Computer Graphics
By Robert Kosara, Fabian Bendix, Helwig Hauser
Issue Date:July 2006
pp. 558-568
<p><b>Abstract</b>—Categorical data dimensions appear in many real-world data sets, but few visualization methods exist that properly deal with them. <it>Parallel Sets</it> are a new method for the visualization and interactiv...
Interactive Focus+Context Visualization with Linked 2D/3D Scatterplots
Found in: Coordinated and Multiple Views in Exploratory Visualization, International Conference on
By Harald Piringer, Robert Kosara, Helwig Hauser
Issue Date:July 2004
pp. 49-60
<p>Scatterplots in 2D and 3D are very useful tools, but also suffer from a number of problems. Overplotting hides the true number of points that are displayed, and showing point clouds in 3D is problematic both in terms of perception and interaction....
User Studies: Why, How, and When?
Found in: IEEE Computer Graphics and Applications
By Robert Kosara, Christopher G. Healey, Victoria Interrante, David H. Laidlaw, Colin Ware
Issue Date:July 2003

Focus+Context Taken Literally
Found in: IEEE Computer Graphics and Applications
By Robert Kosara, Silvia Miksch, Helwig Hauser
Issue Date:January 2002
pp. 22-29
<p>Pointing out relevant information to a user is one application of focus+context techniques in information visualization. The authors present a method for doing this which uses selective blur to direct the user's attention. This method is based on ...
Semantic Depth of Field
Found in: Information Visualization, IEEE Symposium on
By Robert Kosara, Silvia Miksch, Helwig Hauser
Issue Date:October 2001
pp. 97
We present a new technique called Semantic Depth of Field (SDOF) as an alternative approach to focus-and-context displays of information. We utilize a well-known method from photography and cinematography (depth-of-field effect) for information visualizati...
