Accumulative Line Graphs, or Lorenz Curves, show distribution. It can show distribution of things such as income and wealth. I have included a Lorenz Curve which show the distribution of income. It compares the percentage of income to the percentage of households. The blue line represents the line of equality- where 10% of households would be making 10% of the income and so on.  The Lorenz curve shows where the distribution is- in this case less than 60% of the households making 20% of the income.
