Figure 4. Journal distribution in exosomal circRNA research. (A) Journals publishing research on exosomal circRNAs, based on VOSviewer. The closer the label is to yellow, the newer the average publication year of the journal; (B) Distribution of exosomal circRNA research across various co-cited journals, based on VOSviewer; (C) The dual-map overlay of journals on exosomal circRNAs, based on CiteSpace. The citing journals on the left represent the frontier areas of exosomal circRNA research, while the cited journals on the right form the knowledge base of the field. Cited relationships are defined by the connecting lines, with the f-value indicating the citation counts.
