Presets
The Lorenz curve plots the cumulative share of income against the cumulative share of population, from poorest to richest. Perfect equality is the diagonal; the more the curve bows below it, the more unequal the distribution. The Gini coefficient is twice the area between them — 0 is total equality, 1 is one person owning everything.
