One cannot help to compare Tufte’ with Bertin’s books. Both of them knock at the door of the fundamentals of information visualization. However, to understand Bertin’s work, one needs to form systematically logic concepts, pretty similar to studying maths. Whilst Tufte’s book shows us a more pragmatic and narrative view of the evolution of information visualization. And it is more example-oriented. In PART I of this book, it seems that we need to look for answers by ourselves, from the various examples offered by the author. With the several principles that appear at the very beginning, we need to bear in mind of them and even prove them in those examples. What is more interesting is the Graphical Integrity section. The author tries to convince us that even ‘seeing’ might not necessarily be ‘believing’. And besides exercising graphical excellence, we should also pay attention to graphical integrity. These seem to be the two important dimensions when designing graphical display.
