The text is a bit mangled, but it's still better than doing CAPTCHAs. There's a table on Wikipedia if you want to make your own chart.

It helps if you understand Gini coefficients. But in short, they attempt to represent wealth distribution as a scalar from 0 to 1, where 0 is a uniform homogeneous distribution.

So to read the chart, you can tell how big the pie is by how long the bar is, and the non-uniformity in the distribution by how toppled the bar is.
