Research landscape on COVID-19 and liver dysfunction: A bibliometric analysis

Figure 1 Network visualization map of country collaboration. A minimum of 30 documents per country was set as a threshold, and 22 countries met the threshold. Countries can be represented as nodes in a network visualization made with VOSviewer, and lines can be created between the nodes to show correlations between co-occurrences. The strength of the co-occurrence link between the countries can be determined by the line's thickness or weight. Thicker lines are frequently used to depict stronger links.
