📊 Author Alberto Cairo is the Knight Chair in Visual Journalism at the University of Miami's School of Communication, where he teaches data visualization and infographics. 📈 The book was inspired by Cairo's viral Twitter thread debunking misleading charts during the 2016 U.S. presidential election. 📉 The concepts in "How Charts Lie" were tested and refined through a MOOC (Massive Open Online Course) that Cairo developed, reaching over 150,000 students worldwide. 📊 The book examines five ways charts can mislead: being poorly designed, displaying dubious data, showing insufficient data, concealing or confusing uncertainty, and suggesting misleading patterns. 📈 Cairo coined the term "graphicacy" to describe visual literacy specifically related to charts and graphs, arguing it should be considered as important as traditional literacy and numeracy in modern education.
