In the Book of Trees, data visualization expert Manuel Lima (“the man who turns data into art” according to Wired) examines the more than eight hundred year history of the tree diagram, from its roots in the illuminated manuscripts of medieval monasteries to its current resurgence as an elegant means of visualization. Lima presents two hundred intricately detailed tree diagram illustrations on a remarkable variety of subjects—from some of the earliest known examples from ancient Mesopotamia to the manuscripts of medieval monasteries to contributions by leading contemporary designers. In the Book of circles, Lima applies the same approach to circular information design. Three hundred detailed and colorful illustrations from around the world cover an encyclopedic array of subjects–architecture, urban planning, fine art, design, fashion, technology, religion, cartography, biology, astronomy, and physics, all based on the circle, the universal symbol of unity, perfection, movement, and infinity. 208 and 270 pages, 032 LIM.
