Explanation:
(i) The monthly rainfall in a year can be best ’ represented by a bar diagram as only one
variable i.e., monthly rainfall is to be presented diagrammatically. The rainfall is plotted on Y-axis in the corresponding month that is plotted on the X-axis.
(ii) Composition of the population of Delhi by religion can be represented by a component bar diagram. A component bar diagram shows the bar and its sub-division into two or more components. Thus, the total population can be sub-divided in terms of religion and presented through a component bar diagram.
