I finished tufte last night... what a disaster, or perhaps sunk with high expectations.
I'm a huge fan of dr. tufte's very influential writing on information visualization - as far as I know he's done the best work in the field. But this book - while simply physically and visually stunning - is a real disappointment.
In this work I read about 20% insight, 40% recycled material and preaching to what is probably the choir (this includes an overly repetitious chapter-long discussion of minard's lovely march to moscow graphic & his previously available power point piece), and 40% filler & drek. I don't find his comments on art, writing styles, baseball, and the like to be terribly compelling, and are certainly done better in many other works - and indeed, his thoughts on these ended up as being pretty grating and condescending, if not just wrong.
And that the book ends with several pages of photos (a few of really poor quality, I might add) his own outdoor artwork (which are of passable quality, but what the *bleep* does this have to do with evidence as defined at the front of the book?) only throws salt on the wounds.
This thing is maddeningly inconsistent. I wish I could simply dismiss the work, but it's full of beauty and joy as well as the bad. Sparklines are fun, but could be improved on. Words + images combined inline, some great stuff there. But while some of the really lovely things, like the translations of galileo, are wonderful and exciting to any science-loving person, they really are pretty pointless to the conversation at hand. He has gone straight down since his first major book - a 5+ star effort, the 2nd, 4.5-5 stars, 3rd, 3 stars, and this is about a 2 star one (2.5+ if you haven't read the others.)
If he'd stop believing his sycophants and stop taking himself so seriously in his quest to convince the reader that he's a high priest on a moral crusade it'd be wonderful. He really does try to convince the reader that this topic is of high moral concern - not just sometimes, but in general. I don't buy it.
And you shouldn't buy this if you haven't read his other works (although if you haven't I'll admit you'll probably like this, you just don't know any better ;-)). Read the staggeringly good "The Visual Display of Quantitative Information" or the wonderful "Envisioning Information". And if you must read this, soak up the good points, and try not to grind your teeth with the rest.
