Lies, Distortions, and Misrepresentations in Visualization

Visualizations are just another way we communicate. And just like any form of communication, we can use it to lie, mislead, and distort. This session presents overview of some recent work from Tableau Research on how visualizations can deceive, and ways to build "defensive" maps and charts that make sure we're not fooling our audience or ourselves when we look at our data. Drawing on perceptual psychology and statistics, we'll talk about what's hidden in histograms, mendacious in maps, and biased in bar charts. Session Speaker: Michael Correll
