btw sorry pie fans but a pie chart doesnt even look like a pie that just the creators fault, and because of that I have to say pie is bad so yeah sorry bout that ;D
reasons why they should be used more
1. They look and taste better
2. they are cooler B)
3. well donuts are better than pie so... (feel free to object); (usage of pie chart is yellow blue is donut chart); <------- 100 percent real graph; and that concludes my presentation please convince ur teacher to use donut charts :)
