I have been able to find values of Gini coefficient but have not been able to find their corresponding lorenz curves.
Knoema has visualizations of Lorenz curve for a large number of countries, however note if you are doing some research it is expected you will make your own visualizations based on the data.
$\begingroup$ Note that this particular visualization doesn't give you much more information than the Gini coefficient, potentially even less. It plots exactly 5 percentiles, meaning everything in the top 20% is thrown together. So all the plots look visually the same and you can't really see whether there is 20% fairly wealthly people or just 1% who one most of everything. If the Gini coefficient was computed on more finely grained data it might still contain more information. $\endgroup$– quaragueSep 13, 2021 at 13:07
$\begingroup$ @quarague I more or less agree but OP requested these visualizations, maybe you should comment this under the Q $\endgroup$– 1muflon1 ♦Sep 13, 2021 at 16:20
