Global Visa Policies: Creating a Network on a Map with R

Global Visa Policies Recently, I started a new position in a project that aims at developing a typology of border walls at a global scale. Against the backdrop of globalization literature of the 1990s, it has been shown that instead of world that is increasingly ‘borderless’ (Ohmae 1990) we actually observe more and more fortification (Hassner & Wittenberg 2015). While I will certainly write more about this project once it matures, this post features related data that I collected with colleagues at the University of Bremen: The Visa Network Data.
