The New York Times Magazine published an article about marriage infidelities, which I didn't read, but it was popular enough that they did an online poll to obtain some instant feedback from readers. The result was shown in this cutesy graphic:
Note that they plotted the number of responses rather than proportion of responders even though all the numbers are between 0 and 100 and could easily have been misread as percentages.
This chart is another good illustration of the self-sufficiency principle. There is no need to create a chart if all the data are printed onto the chart, and readers must look at the data to learn anything from it. Imagine the above chart without the data, and you'll see why the data labels are critical to this chart.
Below is a version in which I removed all the data labels, replacing them with an axis:
The two pink slabs were thrown in for a little chart-check. According to the designer, 6+6+6 is larger than 20. How is this so? Look at a blow-up of the "God says otherwise" bar of hearts:
The one whole heart in each bar ruins the string of half hearts. Little things can introduce infidelities into charts.
