Question 103140: What Is A Pie Chart?
Answer by MathLover1(20850)   (Show Source):
You can put this solution on YOUR website! A pie chart is a circle graph divided into pieces, each displaying the size of some related piece of information. Pie charts are used to display the sizes of parts that make up some whole.
In a pie chart, the arc length of each sector (and consequently its central angle and area), is proportional to the quantity it represents.
Together, the sectors create a full disk. It is named for its resemblance to a pie which has been sliced.
A part of a circle/pie graph that explains the colors that represent each part or slice of the graph is a legend.
A pie graph (or pie chart) is a specialized graph used in statistics. The independent variable is plotted around a circle in either a clockwise direction or a counterclockwise direction. The dependent variable (usually a percentage) is rendered as an arc whose measure is proportional to the magnitude of the quantity. Each arc is depicted by constructing radial lines from its ends to the center of the circle, creating a wedge-shaped "slice." The independent variable can attain a finite number of discrete values (for example, five).The dependent variable can attain any value from zero to 100 percent.
