The book is

    Cogwheels of the Mind : The Story of Venn Diagrams
    by A. W. F. Edwards (foreword by Ian Stewart)
    Hardcover: 136 pages
    Publisher: The Johns Hopkins University Press (April 26, 2004)
    ISBN: 0801874343

It is a really beautiful book.  There are also some journal articles
on the subject by Edwards and by Branko Grunbaum
(http://www.math.washington.edu/~grunbaum/BG228.pdf)

Edwards is my intellectual grandfather (thesis advisor's thesis advisor),
and it is a pleasure to recommend this book.  (A bit irrelevant to R,
I know, but still ...)
