Tufte's book was recommended to me recently because I create and design maps for my travel guide, "PassPorter Walt Disney World." What a delight it was to find a book that *explains* why it is important to present information clearly, succinctly, and responsibly. I enjoyed it thoroughly, and could only have hoped for more information and examples on maps. You can bet the next edition of my travel guide will have enhanced maps based on Tufte's principles. "Envisioning Information" will have a proud place on my bookshelf for many years to come.
