An International Trade Network (ITN), where the nodes are countries and the ties between them are trade. [Read More]

Recently, I was asked whether I could create an international trade network with flags as nodes. Therefore, I thought I would write a post introducing the ggflags packages and how to use it in network visualisation. I am creating this visualisation in R, and relying on a number of packages: ITNr for the international trade network data that we use in the example. However, you the visualisation steps I will outline can be applied to any country level network (that is a set of countries connect by any links - this could be trade, investment etc. [Read More]
