This repository contains the code and tools needed to generate and visualize information on the relevance of 'primary regions of diversity' of food crops to modern food supplies and agricultural production. The circos diagrams are coded in R, from which .json files are created for use online. The methods and code for the plots were derived from The Global Flow of People by Nikola Sander, Guy J. Abel and Ramon Bauer at the Wittgenstein Centre for Demography and Global Human Capital.
