Instead I give this book regularly to my students & wish to goodness that more of my colleagues had copies. From the opening pages -where Tufte gives us 4 data sets that are statistically indistinguishable but graphicly at different points of the compass- through the beautifully rendered examples of classical and modern examples of meaningful graphics & "chartjunk" Tufte serves as a wry, witty, and informative guide to the perils & joys of informing or confusing an audience with charts and graphs.
Although in some ways a polemic against the misuse of graphical techniques, Tufte never loses his sense of humor & gives us plenty of really GOOD examples as well as a harsh deconstruction of some truly horrendous images. While this, the first in what has become a series, predates the muddy dawn of computer graphical "presentations" the basic principles outlined in its pages are every bit as applicable to the PowerPoint generation as they were to transparencies & posters. Buy it. read it Use it.
