I actually prefer pie charts when information is similar and you're trying to show relative sizes. The example in the article shows why: in the example of the three, it's asking "which segment is biggest?" But that's the point, they are all similar. You don't need to know which one is biggest, or: only if you do need to know that, would it be the wrong way to display information. I'm currently making a budgeting app for my friend, and I'm using pie chart for expenses. We don't need to know "which is the biggest" It's more visually clear that there's broad categories for expenses, and how they sit "relative to the whole" - drawing it as a bar chart would be misleading, because it doesn't show "X is roughly the same size of Q,R,S put together." Without the observer doing some maths and mental "stacking"
