I just wanted to plug for three classical books on statistical graphics that I really enjoyed reading. The books are old (that is, older than me) but still relevant and together they give a sense of the development of exploratory graphics in general and the graphics system in R specifically as all three books were written at Bell Labs where the S-language was developed. What follows is not a review but just me highlighting some things that I liked about these books. So, without further ado, here they are:

- Exploratory Data Analysis by John W. Tukey (1977)
- Graphical Methods for Data Analysis by John M. Chambers, William S. Cleveland, Beat Kleiner and John W. Tukey (1983)
- The Elements of Graphing Data by William S. Cleveland (1985)
