Ultimately it's about truth-telling,

In the spring of 1998, I participated in a semester-long class taught by Edward Tufte.
The subject was information design and his three books, Visual Explanations, Envisioning Information and The Visual Display of Quantitative Information, were the core reading materials of the seminar.
Had I only read the books and not participated in the class, I might have missed some underlying core themes that Tufte conveyed through his passionate presentation of the material.
Beyond just putting the right mark on a piece of paper or on a computer screen, these books are about truth-telling, about removing all impediments to understanding between the communicator and the receiver, and about being selfless in one's representation of the truth.
Similar books just catalog graphical techniques. Tufte's books will leave most readers with an indelible sense of obligation to communicate transparently, selflessly and truthfully.
