Re: Pie Charts (and associated graphical quandaries)

As this will probably "explode" into a juicy discussion, let me bite off a
small slice early. For those who may wish some more background on these
graphical issues -- and they HAVE been seriously considered -- two
references:

Howard Wainer's Book:VISUAL REVELATIONS: GRAPHICAL TALES OF FATE AND
DECEPTION FROM NAPOLEON BONAPARTE TO ROSS PEROT (1997, New York: Copernicus)
is a readable discussion built around many delightful examples. Wainer even
has a kind of pie chart on steroids that he proposes (based on Florence
Nightingale's original version. Yes, that is THE Florence Nightingale of
nursing fame!). See my review of the book in the February, 98 AMERICAN
STATISTICIAN for a quick overview of contents.

A somewhat more statistical but still very readable exposition of graphical
displays can be found in Bill CLeveland's, THE ELEMENTS OF GRAPHING DATA (
1994, New Jersey: Hobart Press. books@hobart.com), in particular, pp.
262-269 on the graphical perception of "Pop Charts."

Enjoy!
