Visualization is the graphic presentation of data -- portrayals meant to reveal complex information at a glance. Think of the familiar map of the New York City subway system, or a diagram of the human brain. Successful visualizations are beautiful not only for their aesthetic design, but also for elegant layers of detail that efficiently generate insight and new understanding. This book examines the methods of two dozen visualization experts who approach their projects from a variety of perspectives -- as artists, designers, commentators, scientists, analysts, statisticians, and more. Together they demonstrate how visualization can help us make sense of the world. * Explore the importance of storytelling with a simple visualization exercise * Learn how color conveys information that our brains recognize before we're fully aware of it * Discover how the books we buy and the people we associate with reveal clues to our deeper selves * Recognize a method to the madness of air travel with a visualization of civilian air traffic * Find out how researchers investigate unknown phenomena, from initial sketches to published papers
