Background The global population hit 8 billion today. To mark the passing an absolute population total I created some animated tree map plots in R to visualize relative past and future population totals for all countries.
I have been playing around with rvest once again, and decided to extend some old code to put together a data base on the squads at past European Championships from Wikipedia.
Background Sankey plots have been used to visualize bilateral migration many times. My favorite examples of Sankey plots for migration data tend to be when there are only few regions or countries.
