A researcher wants to show how the total monthly expenditure of a company is divided among five heads such as salaries, rent and marketing, and also to compare the shares visually. Which diagram is most suitable for showing the parts of a single total?
A pie diagram is the most suitable choice. It divides a circle into sectors whose angles are proportional to each head's share of the total expenditure, so the parts can be compared visually. Histograms, polygons and ogives are meant for continuous frequency distributions instead.

Explanation
A pie diagram divides a circle into sectors proportional to the components of a single total, so it shows the share of each head. A histogram, frequency polygon and ogive are used for continuous frequency distributions, not for splitting a total into categories.
