132        <p>
133            Pie charts can be used when you need to represent a value as part of a whole. It is commonly used to represent percentages,
134            relative magnitudes or relative frequencies. If your intent is to compare a particular value (slice) against the whole of
135            the Pie chart, then it can be quite effective. If however you want to compare two seperate segments, then it can get
136            more difficult. If this is the case, you may want to consider a bar chart for example.
137        </p>
138       
139        <p>
140            The colours can be customised, as can the borders (using the same color as the background and a line width of
141            about 5 gives the effect of segment separation. The chart can also have a drop shadow if you want one, but this shouldn't
142            be used in conjunction with segment seperation.
