The document provides information on choosing appropriate graphs to display data. It discusses bar graphs and pie charts, indicating that bar graphs show distribution to compare categories, while pie charts show composition to illustrate what makes up different components. Examples are provided to demonstrate choosing a suitable graph based on what needs to be shown. For the first example on comparing number of friends based on length of time living in an estate, a bar graph is suggested to show distribution. For the second example on showing races in a block, a pie chart is suggested to show composition. Key words on what needs to be done and how each graph can be used are provided to aid in explaining the graph choice.
