This figure has 3 parts. Part (a) shows a circle divided into sectors of varying sizes. Each sector (pie slice) is filled in a different colour. Part (b) shows a bar chart with vertical bars. The axes are not labelled and there are no units. The vertical axis has a scale from 0 to 400 with equal divisions at intervals of 100. Seven vertical bars are shown, each a different colour and height. Part (c) shows a line chart with a set of axes that have no labels or units. The horizontal and vertical axes are both marked at intervals of 10 from 0 to 60. Various points are marked dots on the graph and these are joined by a straight line between each dot which results in a generally rising line.
