I loved the Ggplot2 when I used it several years ago. But at the time (not sure if it's still true), I found this book essential to understand how to use the library beyond the simple examples.

Seems like the author wanted to be as super transparent as possible. Not sure if that's why it was posted here, but cool in any case.
