Bar charts are another simple way of representing actual data pictorially. A chart is
drawn where labels for the observations are shown on the horizontal (x) axis and the
frequencies of each are shown on the vertical (y) axis subject to the following rules:
Distances against the vertical axis are measurements and represent numerical data.
Horizontal distances have no meaning. There is no horizontal axis or scale, there are
only labels.
