<p>The plots in the figure shows the direct weighted version of the CIMN that highlights the top-ranked destination of each country. The colours of the links represent the proportion of migrant stock in the maximum migrant stock after country of destination [<i>wij</i> / max <i>i</i>(<i>wij</i>)] from light yellow (low-proportion links) to red (high-proportion links). The thickness of the links is proportional to the normalized migrants stocks [<i>wij</i> / max(<i>wij</i>)].</p
