The size of the chosen symbols on a graph may be used to indicate the:
a) location of the data
b) coordinates of the data
c)uncertainty of the data
d)relationship of the variables

D)relationship of the variables

Thus the graph symbols drawn hence show the amount of information that is represented by the bars, lines, and the circles, etc. Bigger symbols on the graph do not matter much as each symbol is represented on the linear pattern. Quantity of data is thus represented in relation to the other symbols on the graph.
