Figure 4 Cooperation map of journals. A: VOSviewer visualization map of the co-authorship network of journals. Visualization map of publications in 90 journals; a node represents one journal, the node size represents the number of publications, a link shows collaboration, and the distance and the thickness of the link between nodes show the relative strength of the relation. The color of each circle is determined by the year of publication; the darker the color, the more recent the publication; B: A dual map overlay of the science mapping literature. A dual map overlay of journals shows the distribution of relationships between journals, citing journals on the left and cited journals on the right, with colored paths connecting them indicating citation relationships and their thickness indicating co-citation strength. The color corresponds to the time when the node was first co-cited.
