Beyond the fact that the neither the white nor gray shaded areas of the donut chart represent 60%?

How does one not catch that... I'd be very accepting of a doughnut graph, if it represented the number it's supposed to represent!

In contrast to your position, I'm not tolerant of donut charts, even when they represent values accurately, because there is almost always a better way to display the data.

I'd much rather just have the number, as it is printed in the middle of the donut chart, without the donut (or any) chart).

jbriggs,

Given the fact that there is only one value on this so-called infographic, I agree that a single number would work best. If a series of proportional values appeared, however, it would make sense to display them using a standard bar graph.

70 ... the new 60?

I find that donut charts like the one above serve as little more than decoration to frame out the value being displayed in the center.  Aesthetically pleasing, yet analytically pointless.

I agree, of course, although I would argue that multiple numbers listed in this format would still be perfectly viable.

I think, for example, that a display like the other recent post in the section ( http://sfew.websitetoolbox.com/post/death-the-ultimate-goal-8292163?pid=1293830786 ), the four numbers there would be better suited as a simple list of numbers than as a bar chart.

jbriggs,

When multiple values are shown that ought to be compared, displaying them graphically as bars makes their differences immediately available to the viewer's eyes, which is often useful. When this isn't useful, the numbers alone usually do the job better.

Stephen - that's essentially what I am getting at.
