6The Truthful Art is an introduction to quantitative thinking and statistical and cartographical representation written specifically for journalists and designers. A follow-up to The Functional Art, it goes into the specifics of how to create functional charts, maps, and graphs.

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; what maps are with an introduction to cartography terms and techniques; the basics of maps including how to create locator maps and how to understand basic cartographical terms such as projection, scale, symbolization, etc.; 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 Naci n (Costa Rica), Estado de S o Paulo (Brazil), and more. He also explains how to develop a successful style book for graphics using sample pages from several real style books for examples.

Part 4, the last section of the book, features interviews with six to 10 leading designers of charts and maps including Jer Thorp, Amanda Cox, Ben Fry, and more.
