As a magazine editor and professor in an earlier life, I much appreciated your recent piece.1 While it was way too short (those damn editors!), the world of graphics--so often done so avoidably poorly--needs all the help it can get.
I was amazed to see no mention (did I miss it?) of the guru in this field, Edward R. Tufte, and his unmatched, brilliantly graphed, texts as examples.2
