Storytelling: The Next Step for Visualization
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.
Parallel Sets: interactive exploration and visual analysis of categorical data
Parallel Sets are a new method for the visualization and interactive exploration of categorical data that shows data frequencies instead of the individual data points, based on the axis layout of parallel coordinates, with boxes representing the categories and parallelograms between the axes showing the relations between categories.

Visualization Criticism - The Missing Link Between Information Visualization and Art

  • 4 July 2007
The idea of visualization criticism bridges the gap between design, art, and technical/pragmatic information visualization, and guides the view away from implementation details and single mouse clicks to the meaning of a visualization. Expand
Metaphors of movement: a visualization and user interface for time-oriented, skeletal plans
This paper developed a visualization and user interface to deal with treatment plans expressed in Asbru, using graphical metaphors to make the underlying concepts easier to grasp, and employ glyphs to communicate complex temporal information and colors to make it possible to understand the connection between the two views available in the system.

WireVis: Visualization of Categorical, Time-Varying Data From Financial Transactions
This paper presents a set of coordinated visualizations based on identifying specific keywords within the wire transactions which demonstrate relationships among keywords and accounts over time and introduces a search-by-example technique which extracts accounts that show similar transaction patterns.

The Shaping of Information by Visual Metaphors
The results suggest that the visual metaphor indeed affects how a user derives information from a visualization, and that the degree to which a user is affected by the metaphor is strongly correlated with the user's ability to answer task questions correctly. Expand
The Connected Scatterplot for Presenting Paired Time Series
This work describes how paired time series relationships appear in a connected scatterplot, qualitatively evaluates how well people understand trends depicted in this format, and quantitatively measure the types and frequency of misinter pretations. Expand
Pargnostics: Screen-Space Metrics for Parallel Coordinates
Pargnostics, parallel coordinates diagnostics, a model based on screen-space metrics that quantify the different visual structures that are observed in parallel coordinates is proposed, providing a way of automatically optimizing the display according to the user's preferences based on the metrics and model. Expand
Parallel sets: visual analysis of categorical data
Parallel sets is a new visualization method that adopts the layout of parallel coordinates, but substitutes the individual data points by a frequency based representation, which allows efficient work with meta data, which is particularly important when dealing with categorical datasets. Expand
Focus and Context Taken Literally
The authors present a focus+context method that blurs objects based on their relevance (rather than distance) to direct the user's attention. Expand
