This work is better summarized with a brief description of the chapter titles rather than delving into the specifics Tufte gives. The work is concise, and easy to reference, and summarizing it in that light feels pointless.

Part I Graphical Practice

The first part is broken up into three chapters:

1 Graphical Excellence, in which Tufte provides examples of excellent graphics, and details on why they are excellent.

2 Graphical Integrity, which discusses graphics that lie.

3 Sources of Graphical Integrity and Sophistication.

Part II Theory of Data Graphics

This part goes into the more detailed theory of actually creating good Data Graphics. I will list the chapter titles:

4 Data-Ink and Graphical Redesign

5 Chartjunk: Vibrations, Grids, and Ducks

6 Data-Ink Maximization and Graphical Design

7 Multifunctioning Graphical Elements

8 Data Density and Small Multiples

9 Aesthetics and Technique in Data Graphical Design

Epilogue: Designs for the Display of Information
