We present a combination of techniques from molecular, flow, and scalar data visualization to reveal the characteristics and processes in the data of this year’s IEEE scientific visualization contest. Among the challenges we had to address were the strong thermal vibration of the molecular data as well as the fact that the simulated material did not behave as we would have expected according to...

Volume visualizations can have drastically different appearances when viewed using a variety of transfer functions. A problem then occurs in trying to organize many different views on one screen. We conducted a user study of four layout techniques for these multiple views. We timed participants as they separated different aspects of volume data for both time-invariant and time-variant data usin...

A curriculum designed to educate those who design, develop, and deploy scientific visualizations and/or visualization tools needs to contain a strong component of both human-computer interaction and human cognition. The argument centers around two observations. The first is the rapidly increasing breadth of application for computer-based visualizations and the tools for creating them. The secon...

The basic objective of data visualization is to provide an efficient graphical display for summarizing and reasoning about quantitative information. Data visualization should be distinguished from other types of visualization used in political science (more general information and knowledge visualization, concept visualization, strategy and workflow visualization, metaphor visualization, etc.) ...

Knowledge-assisted visualization has been a fast growing field because it directly integrates and utilizes domain knowledge to produce effective data visualization. However, most existing knowledge-assisted visualization applications focus on integrating domain knowledge that is tailored only for specific analytical tasks. This reflects not only the different understandings of what “knowledge” ...

Processing is a programming language and environment targeted at artists and designers. It is used in various environments for different purposes, from scientific data visualization to art installations. This paper is comprised of two parts. The purpose of the first part is to provide an insight into Processing and its community as well as to showcase some projects that were created using Proce...

Although there are a number of visualization systems to choose from when analyzing data, only a few of these allow for the integration of other visualization and analysis techniques. There are even fewer visualization toolkits and frameworks from which one can develop ones own visualization applications. Even within the research community, scientists either use what they can from the available ...
