To draw a pie chart, we need to represent each part of the data as a proportion of 360, because there are \(360^{\circ}\) in a circle. For example, if 55 out of 270 vehicles are vans, we will ...

A Pie is a circle, which is 360 degrees ... But, if this Pie chart represents people, then C which is 90 degrees isn’t 90 people. And 90 degrees isn’t 90 percent! Be careful!

we then divide 360 by 12, making the maximum number of degrees by sign or planet 30. These degrees come in handy when trying to determine one’s persona and understand their birth chart.
