In this follow-up to his hugely popular The Book of Trees and Visual Complexity, Manuel Lima takes us on a lively tour through millennia of 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, wholeness, infinity, enlightenment, and perfection. Clay tokens used by ancient Sumerians as a system of recording trade are juxtaposed with logos of modern retailers like Target; Venn diagrams are discussed alongside the trefoil biohazard symbol, symbols of the Christian trinity, and the Olympic rings; and a diagram revealing the characteristics of ten thousand porn stars displays structural similarities to early celestial charts placing the earth at the center of the universe.

Lima's introduction provides an authoritative history of the circle, and a preface describes his unique taxonomy of the many varieties of circle diagrams, rounding out this visual feast for infographics enthusiasts.
