This type of graph, also known as a pie chart, is most commonly used to show the breakdown of items in a budget. Such a graph would show the same relative population sizes as the bar graph, but it would also illustrate that approximately one-fourth of the world’s population resides in China. This same information may be expressed in a part-to-whole relationship by using a circular graph, in which a circle is divided into sections, and where the size, or angle, of each sector is directly proportional to the percentage of the whole it represents. Thus, a demographer could see at a glance that China’s population is about 30 percent larger than its closest rival, India. The length of each bar would be proportional to the size of the population of the respective country it represents. To illustrate the relative populations of various nations, for example, a series of parallel columns, or bars, may be used. If the independent variable is not expressly temporal, a bar graph may be used to show discrete numerical quantities in relation to each other.
