proportionately divided to represent different sub-factors of any data. it
is drawn on the basis of given statistical values. Generally data is in
the form of percentage.

percentage form, they should be converted into percentage. The total area
of the rectangle is considered as 100% and it is divided according to the
percentage of each sub-factor.
Since each sub unit which
is shown in the rectangle has a separate identity, each one can be shaded
differently and a legend can be given to understand it easily.
