Since I was already making these figures, might as well submit them for the #30DayChartChallenge Day6: #OWID.

CO2 emissions by regions and countries. Made in #Stata using the #treemap package (https://github.com/asjadnaqvi/stata-treemap). One of the hardest ones to code but it's pretty solid now.

In a similar vein, it's distance cousin "circlepack" (https://github.com/asjadnaqvi/stata-circlepack),
is also very stable, but needs enchancements, similar to treemap, to deal with large amounts of labels. Once there is time, it will be updated :)
