Tufte's volumes is an iconic volume for graphic design that unites legibility with efficiency and beauty in a cogent and stimulating manner. While it's reputation and overwhelming authority may hurt it a bit, it is actually a worth read with a well develop and constructed analysis - with a breakdown of some "best and worst" practices" - and an intriguing attempt to develop a theory for data graphics, which for the most part is worth carrying around and promoting.<br><br>Among some of the most obvious defects is a repetition of some trends and examples, a patronizing sense that permeated the narrative here and there, and with that, touches that may seem that the critique is trying to be too final, and offers little room for debate. But all in all these touches are minor and the volume withstands as a pivotal critical point to develop legible and useful graphic information. Something that I would recommend to anyone involved with, or interested in these aspects.
