Graphical excellence is that which gives to the viewer the greatest number of ideas in the shortest time with the least ink in the smallest space.
This book is a classic of how to design a good graphic. It contains some of the most inspirational graphics ever seen and Tufte puts the basis of what makes informational design beautiful and practical.
The content is mostly graphs and charts from the 1970s (even though the second edition is from 2001), which contain the main ideas of a good or a bad chart, but more contemporary design would have been more entertaining.
The designs presented are elegant and powerful, but sometimes forget about the new displays of space, fonts, colours, images, movement.
I was impressed by the simplicity and power of some charts made in the 18th and 19th century, by pencil and rule. They expressed ideas so strongly, only using good use of images, numbers and space.
A good design cannot supplement bad information, but a good design can made good information, memorable.
