Pie Map Definition


Pie maps can be drawn for areas, points, or curves and are a way to represent several data values by drawing a proportionally sized pie chart for each object. Pie charts show two or more variables where each variable is represented by a proportionally sized slice of the pie. Within a single pie, the size of the slices gives you the relative proportion of the values for that particular object. The entire pie chart is sized in relation to the total of all variables for that object, as compared to the totals of the variables for other objects.
