Circles or pie diagrams are alternative to squares. These are used for the same purpose i.e. when the values are differing widely in their magnitudes. These diagrams are more attractive then circles. Thus pie diagrams are preferred to square diagrams .Both these diagrams involve the same amount of labour.
