Visual Explanations
Tufte's 1997 third book — extending the framework into the domain of causality and evidence, containing the definitive analysis of the Challenger charts and introducing the ethics of evidence presentation in high-stakes decision-making.
Visual Explanations is Tufte's most explicitly ethical book. Where The Visual Display of Quantitative Information addressed the mechanics of graphical excellence and Envisioning Information addressed multidimensional representation, Visual Explanations addresses the presentation of evidence in contexts where consequential decisions depend on the quality of the display. The book's centerpiece is the definitive Tufte analysis of the Challenger charts, a reconstruction of the information-design failures that contributed to the January 1986 disaster. The book also examines John Snow's 1854 cholera investigation, magic tricks and their relationship to visual evidence, and the general problem of presenting dynamic processes on static media.

The Challenger analysis occupies a central chapter and is the most widely cited case study in the history of information design. Tufte reconstructed the thirteen charts Morton Thiokol engineers presented to NASA the night before the launch and demonstrated, with painful precision, how the format buried the correlation between low temperature and O-ring damage that would have prevented
