Pie charts represent the value of the individual items with respect to the total items and is built from a single dimension and measure only.
The Pie chart displays the relationship between values as well as the relation of a single value to the total. You can use a Pie chart when you have a single data series with only positive values. Envision allows you to add a secondary analysis dimension on the same pie using the slice height method.

Pie charts are particularly useful for comparing a certain sector with the total. It provides an instant understanding of proportions when few sectors are used as dimensions, for example, 'queued/finished', or 'in-time/delayed/cancelled' to retain its visual efficiency.
However, it is often hard to compare the results of two Pie charts, or different sectors of a Pie chart, especially in a chart with many sectors. Also, the Pie chart takes up more of chart space in comparison to the values it visualizes.
