Bipartisanship Breakdown, Functional Networks, and Forensic Analysis in Spanish 2015 and 2016 National Elections

Figure 6

First-level communities obtained via community detection algorithm Infomap, performed on the thresholded, undirected, and weighted network based on the similarity matrix S (see the text). Here we color nodes belonging to the same community in the same color. There is an appreciable matching between functional network communities in the network of municipalities and actual Spanish autonomous communities, although this correspondence is much more evident for the 2015 round, where bipartisanship breakdown was at its zenith.
