The rectangular method of diagrammatic presentation is
difficult to use where the values of items vary widely. The method
of drawing a square diagram is very simple. One has to take the
square root of the values of various item that are to be shown in the
diagrams and then select a suitable scale to draw the squares.
Example 7:
Yield of rice in Kgs. per acre of five countries are

Another way of preparing a twodimensional diagram is in
the form of circles. In such diagrams, both the total and the
component parts or sectors can be shown. The area of a circle is
proportional to the square of its radius.
While making comparisons, pie diagrams should be used on a
percentage basis and not on an absolute basis. In constructing a pie
diagram the first step is to prepare the data so that various
components values can be transposed into corresponding degrees
on the circle.
The second step is to draw a circle of appropriate size w...
