The Truthful Art is an introduction to data reasoning and statistical and cartographical representation written for anyone who wishes to communicate effectively, including journalists, graphic designers, scientists, and business professionals. A follow-up to The Functional Art, it goes into the specifics of how to design appealing, credible, and informative infographics and data visualizations. Part 1 in The Truthful Art provides a broad introduction to statistics, written with journalists and designers in mind. Cairo avoids using jargon and formulas, focusing instead on how to manage and interpret data sets, and how to extract stories from them. In Part 2, Cairo gets down to business giving specific advice on how to use charts and maps in infographics and visualization. Readers will learn what kind of statistical charts exist and how to use them correctly; how to talk about maps, with an introduction to cartography terms such as projection, scale, and symbolization; the basics of making maps, including how to create locator maps; and the main kinds of thematic maps (choropleth, isopleth, proportional symbol, etc.) and how to use them. In Part 3, Cairo leaves the classroom and enters the real world with an in-depth look at how information graphics and visualization teams are organized at publications around the world including The New York Times, La Nación (Costa Rica),Estado de São Paulo (Brazil), and more. He also explains how to develop a successful style book for graphics using sample pages from several real style books as examples. Part 4, the last section of the book, features interviews with leading designers of charts and maps including the talented Jer Thorp, Amanda Cox, Ben Fry, and more.
