I'm not sure I can give you an example where a pie chart gives you more info than a take. What a pie chart does do is convert information fairly quickly. Personally I think you should use it basically for percentages only (or similar situations) it makes it fairly easy to see if one piece of pie is larger than another. Sure a bar chat y does the same, except a bar chart didn't let you easily know the percentage. Sure you can say 25% in the label or something. But a pie chart makes it obvious. A table is cool, but it takes longer to process it.
