How to Lie with Charts – part 2

What is (I think) very educational is that he also asked them to look at color theory, word-image association, juxtaposition, and other aesthetic methods of influencing meaning and interpretation.

Forbes : Graph Makeover Contest
Naomi Robbins on Forbes.com presented a graph and a table and asked readers to present alternatives.
