Like its predecessors, Visual Explanations is both intellectually stimulating and beautiful to behold. Tufte, a self-publisher, takes extraordinary pains with design and production. The book ranges through a variety of topics, including the explosion of the space shuttle Challenger (which could have been prevented, Tufte argues, by better information display on the part of the rocket's engineers), magic tricks, a cholera epidemic in 19th-century London, and the principle of using "the smallest effective difference" to display distinctions in data. Throughout, Tufte presents ideas with crystalline clarity and illustrates them in exquisitely rendered samples.
