A quick post with no content of my own:
Seth Godin, professional agent provocateur, has caused something of an outcry amongst data visualisation aficionados in a blog post lambasting the use of bar charts in presentations. Although his heart is in the right place, Godin's somewhat simplistic prescriptions for improving communication effectiveness miss the mark. Perhaps his greatest crime is to advocate the use of pie charts, which, as we know, are as "professional as a pair of assless chaps." The boys at Juice Analytics and Stephen Few have the scoop.
