I recently bought a copy of The Visual Display of Quantitative Information by Edward R. Tufte (Graphical Press LLC, Cambridge, USA). Tufte's website gives quite a bit of information on his publications.
Edward Tufte has written several books, generally on the effective graphical display of data. This volume is the first of a series of four, and was originally published in the late 80s (I have the second edition, fourth printing, 2006), before the appearance of Microsoft's PowerPoint application.
