Circular Migration Flow Plots in R

Guy Abel and Nikola Sander have recently published in the journal Science their paper on Quantifying Global International Migration Flows (ht MetroPop, by Ramon Bauer). 

Inspired by Martin Krzywinski's Circos and Mike Bostock’s D3.js library, they came up with this beautiful and interactive visualization of circular migration flow between 196 countries from 1990 through 2010.

You may download the data and find more information on the plot here. Abel also talks about the code he has used here and here to make similar charts in R (not interactive though). 

As I've mentioned in another post, it's not everyday you see demographers publishing on journals like Science and Nature. This paper will add to the massive presence of @IIASAVienna and @WiCVienna researchers in these two journals.
