Accumulative line graph

http://vlab-resi.tamu.edu/simseg/overview/demog.htm

An accumulative line graph, or Lorenz curve shows the proportion of distribution by a certain percentage of the bottom variable. It shows how far each subset group deviates from the line of equality. In this Lorenz curve, the socioeconomic status of each group is being measured. The further each curve differs from the straight line of equality, the greater the inequality in the groups status distribution.
