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).
