Scott Weingart reviews Manuel Lima, The Book of Trees: Visualizing Branches of Knowledge (Princeton 2014:
Lima’s book is a history of hierarchical visualizations, most frequently as trees, and often representing branches of knowledge. He roots his narrative in trees themselves, describing how their symbolism has touched religions and cultures for millennia. The narrative weaves through Ancient Greece and Medieval Europe, makes a few stops outside of the West and winds its way to the present day. Subsequent chapters are divided into types of tree visualizations: figurative, vertical, horizontal, multidirectional, radial, hyperbolic, rectangular, voronoi, circular, sunbursts, and icicles. Each chapter presents a chronological set of beautiful examples embodying that type.
