The three-dimensional rendering of this pie chart is gratuitous, and pie charts are bad anyway, as humans are notoriously poor at comparing areas. The color is gratuitous, too. Any graph that is meaningful only if the numbers are also cited must be viewed as a failure. That the figure is obviously from Microsoft Excel is another embarrassment.
The authors could have just cited the numbers. Alternatively, a bar plot (without gratuitous 3D) wouldn't be unreasonable.
