The article writer contradicts him/herself when they emphasis "simplifying" infographics (with the animated gif example), but their favorite infographic at the moment is the Microsoft/Nokia example they showed. That infographic contains a pie chart.

Pie charts are hard to read and to compare size. As you can see in that example, for you (the user) to gather the information, you need to see the percentile, then also look at the legend outside the pie chart. A bar graph would've conveyed the information more efficiently.
