Figure 5 Co-occurrence clustering keyword network. Each node represents a keyword, and the connection between keywords represents the co-occurrence relationship. The nodes with different colors in the clustering style represent different clusters. To clearly indicate the scope of a cluster, CiteSpace uses polygons to add shading to the clusters, which shows the boundaries of the clusters.
