Represent the following frequency distribution by bar graph:
`{:("Value of Variable",3,6,9,12,15),("Frequency",6,10,4,3,8):}`

Explanation

Either of the following bar graphs [Fig. 9.1(a) or Fig. 9.2(b)] may be used to represent the above frequency distribution. The first graph takes value of the variable along the X-axis and the frequency along the Y-axis, whereas the second one takes the frequency along the X-axis and the value of the variable on the Y-axis.
All the rectangles (bars) should be of same width and uniform spaces should be left between any two consecutive bars.
