Composition charts are used to illustrate how individual parts make up the whole. This is usually done in percentages, with all the segments equaling to 100%. Composition charts can also be used to show how a total value can be divided into parts or to highlight the significance of each part relative to the total value. Be careful not to divide into too many parts, or have value differences between parts that are too big.
