This book was written for statisticians, computer scientists, geographers, research and applied scientists, and others interested in visualizing data. It presents a unique foundation for producing almost every quantitative graphic found in scientific journals, newspapers, statistical packages, and data visualization systems. This foundation was designed for a distributed computing environment (Internet, Intranet, client-server), with special attention given to conserving computer code and system resources. While the tangible result of this work is a Java production graphics library (GPL) developed in collaboration with Dan Rope and Dan Carr, this book focuses on the deep structures involved in producing quantitative graphics from data. What are the rules that underly the production of pie charts, bar charts, scatterplots, function plots, maps, mosaics, radar charts? These rules are abstracted from the work of Bertin, Cleveland, Kosslyn, MacEachren, Pinker, Tufte, Tukey, Tobler, and other theorists of quantitative graphics. Those less interested in the theoretical and mathematical foundations can still get a sense of the richness and structure of the system by examining the numerous and often unique color graphics it can produce. Leland Wilkinson is Senior VP, SYSTAT Products at SPSS Inc. and Adjunct Professor of Statistics at Northwestern University. He wrote the SYSTAT statistical package and founded SYSTAT Inc. in 1984. Wilkinson joined SPSS in a 1994 acquisition and now works on research and development of graphical applications for data mining and statistics. He is a Fellow of the ASA and an Associate Editor of The American Statistician. In addition to journal articles and theoriginal SYSTAT computer program and manuals, Wilkinson is the author (with Grant Blank and Chris Gruber) of Desktop Data Analysis with SYSTAT.

In traditional computer graphics, 3D objects are created using high-level surface representations such as polygonal meshes, NURBS patches, or subdivision surfaces.However, these methods often do not account for light interaction that is taking place in the atmosphere or in the interior of an object. Contrary to surface rendering, volume rendering describes a wide range of techniques for generating images from 3D scalar data. These techniques generate high-quality images of volumetric objects in real time, including local and global illumination effects.This book provides the basic theory and practical examples needed to work with volume graphics by taking advantage of today's graphics hardware to produce stunning results in real time. The authors provide: • A practical introduction to texture-based volume rendering • Methods for integrating different aspects of light/matter interaction • Global illumination techniques • Optimization strategies • Code samples—and more!
Introducing readers to different ways of ordering all of the projects they are working on, "Manage Your Project Portfolio" helps to define a team's, group's, or department's mission--whether the projects include of software or hardware applications.

Science and art have in common intense seeing, the wide-eyed observing that generates empirical information. Beautiful Evidence is about how seeing turns into showing, how empirical observations turn into explanations and evidence presentations. The book identifies excellent and effective methods for presenting information, suggests new designs, and provides tools for assessing the credibility of evidence presentations.Here we will see many close readings of serious evidence presentations-ranging through evolutionary trees and rocket science to economics, art history, and sculpture. Insistent application of the principles of analytical thinking helps both insiders and outsiders assess the credibility of evidence.
