Aighly practical guide to the graphic representation of quantities, locations, connections and other forms of data, founded on solid design principles. Easy to understand, the book has been created to assist designers, researchers, and writers in expressing visually through points, lines, and areas that which by words, letters, and numbers alone often have difficulty communicating. It describes problems, principles, and solutions for the visual display of information, and presents real-world didactic examples, taken from, for example, the Financial Times and the Wall Street Journal. The book's theoretical basis is strong, but not at the expense of clarity; readers will understand both what to do and why. After a number of introductory chapters that describe what is common to all types of visual displays, the book continues with three main parts that deal with displays showing quantities, locations, and connections. Data Design is an essential guide to how data can, and should be, presented in order to effortlessly communicate information with clarity, elegance and style. Highly illustrated and with beautiful simplicity, Data Design is an indispensable guide to the clear and effective presentation of information.
