# ---------------------
# This is the R script that generates the charts, maps and tables for the Datawrapper blog post, written by Lisa Charlotte Rost.
# This is NOT great R code. It works, but much of it could have been achieved with shorter code, more elegant, more efficiently, less confusing and without so many libraries; especially the further you go down the script (I got better in the process, among others thanks to my coworker Gregor Aisch who's still a R pro). Please don't use this code to learn R.
