Global scientific trends on hepatocellular carcinoma research from 2004 to 2023: A bibliometric and visualized analysis

Figure 4 Network visualization map of the 44 most productive journals on hepatocellular carcinoma. Visualization map of publications across 44 journals. Each node represents an individual journal, where the circle size corresponds to the publication volume (larger circles indicate higher publication counts). Node color represents citation frequency, with a gradient from blue to red indicating increasing average citation counts from low to high. The thickness of the links denotes the collaboration strength, with thicker lines indicating a higher degree of cooperative activity between the two journals.
