This podcast discussed Tufte's book, which explores the design of statistical graphics and how to communicate information through them. The author, who self-published the first edition of this book, argues that data graphics should show the data and induce the viewer to think about the data, not the graphic production method, graphic design or technology used to make the graphic. The book provides practical examples of graphical excellence, a theory of data graphics1, and a discussion of graphical integrity using examples from maps, scientific publications, newspapers, and historical sources. The author concludes that in order to achieve graphical excellence, the designer must tell the truth about the data, maximise the data-ink ratio and revise and edit their work
