Good Visualization Image:goodvis1.jpg

Source: "For Non-English Speakers, Drug Label Instructions Can Be Lost in Translation", by Mike Mitka, JAMA, 6/20/2007, Vol 297, No. 23, pg. 2575

Motivation: In a journal tailored for English speaking readers, this image in Korean makes it very clear that most readers would have a great deal of difficulty in understanding the drug, the dosage size, the number of times per day to take the doses, etc., if faced with that information in Korean. In the same way, non-English speaking patients would look at an English instruction set and be bewildered about their dosing instructions.


Bad Visualization Image:badvis1.jpg

Source: "Why Don't Inventors Patent", by Petra Moser, National Bureau of Economic Research, Working Paper 13294, August 2007. This plot depicts, for a variety of cities, their population and percentage of submitted exhibits that were patented, for the years 1841-1851, with the population derived from the 1851 census.

Motivation: Because of the density of points in the lower population ranges, and the sparsity at the higher ranges, it is practically impossible to determine anything about relationships or lack of relationships between city size and the percentage of patented exhibits. Many improvements could be made, by binning, examining quantiles, or other means. Another issue is that although percentages are displayed on the Y-axis, there is no way of knowing if the number of exhibits is small or large. It's very likely that the numbers are quite small, especially to have so many points clustered at 100%, 50% (1/2, 2/4, etc), 66% & 33% (2/3, 1/3), 20% and 25%.
