This book is intelligent and wise, clear and beautiful, stimulating and useful. It distills and presents in one place a mountain of research results and tried-and-true best practices. It is an invaluable resource for anyone interested in visual communication.
I love the economy of expression in Per Mollerup's writing. He applies the classic Danish design approach (modern but human) to the explanation of design, isolating the essence of a topic, then explaining it simply. This book joins his seminal 'Wayshowing' as an essential text.
With the key words communicate, record and understand, Mollerup guides the reader in how to design complex data to facilitate the interpretation act. Generous well-designed visualizations and explanations work together as useful guidelines for anyone that frequently presents quantities, locations and connections.
