From: The higher education space: connecting degree programs from individuals’ choices
The Higher Education Space for (a) Portugal, from 2008 to 2015 and for Chile, for (b) 2006 to 2011 and (c) 2012 to 2017. Following the 2012’ addition of 9 new universities, the Chilean HE system was divided into two distinct networks (see Additional file 1). The color of the nodes identifies the Education Field of the degree program according to the first level of the International Standard Classification of Education (ISCED). Sizes of nodes illustrate the relative number of observations in relation to other degree programs in the same network, sizes of nodes are not comparable among different networks. Network layouts have been obtained using the SpringElectricalEmbedding algorithm implemented in Wolfram Mathematica
