The visualization presents an author citation network map created using “V O S viewer”, featuring several clusters of authors connected by a dense web of curved linking lines. On the left side of the map, a large, prominent node labeled “Wagstaff” serves as a major hub, surrounded by and connected to authors such as “Mills”, “Mcintyre”, “Lindelow”, and “Karan”. Directly below this group is another cluster containing nodes like “Criel”, “Hanson”, “Ridde”, “Who”, “Imf”, “De allegri”, and “Mckee”. In the center-right area, a large, dense cluster features authors including “Gruber”, “Manning”, “Baicker”, “Currie”, and “Sommers”. Between the central and left groups, nodes such as “Yip”, “Wang”, “Zhang”, “Liu”, and “Hsu” act as bridges. Co-citation analysis. Source(s): Authors’ compilation using VOSviewer
