Accumulative Line Graph / Lorenz Curve

 
 
The Lorenz Curve (Accumulative Line Graph) is formed by plotting the cumulative distribution of the amount of the variable concerned against the cumulative frequency distribution of the individuals possessing the amount. In the geography realm this map type is used to study biodiversity.
The image above is considered an Accumulative Line Graph / Lorenz Curve. This cumulative frequency curve shows the distribution of a variable such as population against an independent variable such as income or area settled. If the distribution of the dependent variable is equal, the plot will show as a straight, 45° line. Unequal distributions yield a curve.
