A donut chart is a kind of chart that is used to compare prices or other kind of financial data. It looks like a donut and this is why it is called a donut chart. So, have you ever used a donut chart? How often do you use it?

 

[Ja Sa Bong]

I've never heard anything about a donut chart before now. I never knew there any chart called donut chart in all my years of studying economics. I've not used it in my business because I don't know what it looks like or how it's used.
