A graph which consists of a circular region partitioned into disjoint sections, with each section representing a part or piece of the whole.

(Categorical Data) To show the division of a whole into parts.

Daniel Gomez

A diagram consisting of rectangles whose area is proportional to the frequency of a variable and whose width is equal to the class interval.

(Numerical Data) To compare numbers of data items grouped in numerical intervals; order matters in the data depicted.
