Dynamic Color Mapping of Bivariate Qualitative Data
- …Color is widely and reliably used to display the value of a single scalar variable. It is more rarely, and far less reliably, used to display multivariate data. Dynamic control over the parameters of the color mapping results in a more effective environment for the exploration of multivariate spatia…

Task-Based Color Scale Design
- …Color is commonly used in data visualization in order to convey a wide variety of types of information: metric values, pattern, extrema, emphasis, and others. A distressingly large percentage of these visualizations appear to use the default color scale for the visualization package used to create t…

Perceptual Principles for Effective Visualizations
- …This paper presents a number of perceptual principles for the construction of effective visualizations. Principles are demonstrated in example images. In the example images, value is represented by color, height, position, or opacity. Other representation parameters are certainly possible, but are n…

ABSTRACT Visualizing Trends in Student Performance Across Computer Science Courses
- …Student retention is an important topic in Computer Science departments across the country. Keeping strong students and helping struggling students perform better are two fundamental components of improving retention. Isolating the cause(s) of students leaving the major is an important area of resea…

Visualization of Molecules with Positional Uncertainty
- …. Designing new and better chemotherapeutic compounds requires an understanding of the mechanism by which the drugs exert their biological effects. This involves consideration of the geometry of the active site, determination of the geometry of the drug, and analysis of the fit between them. This pr…

Probabilistic Surfaces: Point Based Primitives to Show Surface Uncertainty
- …Efficient and informative visualization of surfaces with uncertainties is an important topic with many applications in science and engineering. Examples include environmental pollution borderline identification, identification of the limits of an oil basin, or discrimination between contaminated and…

Volume Illustration: Non-Photorealistic Rendering of Volume Models
- …Accurately and automatically conveying the structure of a volume model is a problem not fully solved by existing volume rendering approaches. Physics-based volume rendering approaches create images which may match the appearance of translucent materials in nature, but may not embody important struct…
