These principles were defined by [[Edward Tufte]] in his book *Beautiful Evidence*. [^Tufte] 1. Show comparisons, contrasts, differences. 2. Show causality, mechanism, explanation, systematic structure. 3. Show multivariate data; that is, show more than 1 or 2 variables. 4. Completely integrate words, numbers, images, diagrams. 5. Thoroughly describe the evidence. Provide a detailed title, indicate the authors and sponsors, document the data sources, show compete measurement scales, point out relevant issues. 6. Analytical presentations ultimately stand or fall depending on the quality, relevance, and integrity of their content. [^Tufte]: [[Edward Tufte]]. 2006. *Beautiful Evidence*.
