Chord diagram showing migration links between countries from our data. Each country is represented by an arc in the circle, with a country-specific colour. For instance, the largest arc corresponds to the US. Each chord has a starting point in the nationality country, with the same colour of the chord, and the end point in the destination country, with a different colour. The width of the chord represents the relative number of the 2018 migrants with a specific nationality and residence. For example, the widest light blue chord leaving the US reaches Great Britain, marked by the arc coloured in pink. For visualisation purposes, we show only 21 countries: those with at least 10 migrants. Note that this diagram is not representative of global patterns but only shows the structure of our data
