Group-wise overlay of scatterplot combined with marginal distribution on the sides using Stata

Visualization in Stata that displays how countries with the highest vulnerability to climage change have the lowest CO2 emissions.

Using Asjad Naqvi's Delaunay Package, I generate a scatterplot that encircles all the points on a scatterplot by group. The example makes use of default dataset and creates a rubber band like plot around group points in Stata. The method is not clean and neat but does the trick for now.
