Exercise 2: Pie Chart

Pie chart: A pie chart (or a circle chart) is a circular statistical graphic, which is divided into slices to illustrate numerical proportion.

In a pie chart, the arc length of each slice (and consequently its central angle and area), is proportional to the quantity it represents.

Pie charts represent a whole amount that equals 100%. If you were to add up the percentages of each sector, it would equal 100%.

Exercise 2: Pie Chart

Pro-tip:

There's a small number of slices.

If your data has more than 10 or so slices, that's probably too many.

Bad use of pie-chart
