Asian net Migration and Remittance Networks. (a) Each edge in the Asian net migration network is weighed using a weight function similar to equation 1, and colored according to increasing weight from red to blue. Country abbreviations are as in Table 1. (b) The directed graph of the Asian net remittance network is constructed similarly. (c) A circular flow of migrant surplus between Tajikistan, Kazakhstan, and Kyrgyztan. (d) Net remittance flow among Indonesia, India, Malaysia, Saudi Arabia, and Singapore. (e) An example of a more complex flow of migrant surplus among groups of countries in Asia. Each triangle is colored according to flow magnitude, and graded with respect to flow direction. (f) An example of the complex flow of remittance surplus among groups of countries in Asia
