The line graph shows the Gini inequality index for a number of countries, and allows you to explore how they change over time.
The Gini Index is a measurement of income inequality ranging between 0 and 100. A rating of 0 represents perfect equality, and 100 represening perfect inequality.
I have highlighted a couple of countries: India, and the USA, but you can have a look at others by hovering your mouse pointer over the lines.
