Figure 8. Map of the Network-based riskindex pop here was considered the swine population in each municipality from SC, Brazil. The maps are faceted by SNA parameter (Degree, Betweenness, Closeness and finally Rev(PageRank)).
Communities
Communities are sets of nodes (municipalities in this case) that interact more frequently with one another than with nodes from other communities. The spatial distribution and the proportion of the movements within communities are shown in figure 9. The modularity value was 0.35, indicating a moderate community division. As shown in figure 1, there are no premises located in certain municipalities and therefore they could not be assigned to a specific community (NA in figure 9b).
