A Graph That Will Give You a Headache
A graph is intended to provide facts in a straightforward and easy-to-understand manner. That is not to say they are immune to design gaffes. This graph depicted the frequency with which various shoe colors were worn. This seems to be a bit tricky to decipher the true intent of this graph.
However, unless you examine the lower axis, you may be puzzled by the true results. It appears as though it would be simpler and more succinct to just add bars to the chart in tones that correspond to the colors they represent. This would help determine the statistics and the data that has been presented in the chart.
