The network displays multiple clusters of nodes, each represented by circles with labels, connected by thin lines indicating relationships, with labels adjacent to the nodes. At the center, a dense multicoloured cluster appears where nodes such as “barnett (2006)”, “mackey (2007)”, “xie (2019)”, “okafor (2021)”, “hou (2019)”, “huang (2021)”, and “indrasit (2018)” sit closely together, forming the core of the interconnected structure. Surrounding this central area, numerous yellow, green, blue, and red nodes overlap through curved linking lines. To the left of the central cluster, a prominent green grouping includes larger nodes such as “vogel (2005)”, “landi (2019)”, and “nakamura (2015)”, along with several medium and small green nodes including “marti (2015)”, “charlo (2015)”, “hoang (2020)”, “zhou (2022)”, and “le (2023)”. On the upper right, a blue-coloured cluster emerges, composed of nodes labeled “jeffrey (2019)”, “barauskaite (2021)”, “b?tae (2021)”, “naseem (2020)”, “uyar (2020)”, “anser (2018)”, and “garcia (2020)”. On the right side, a large red cluster extends outward with “wang (2017)” serving as the central red node. This red grouping contains surrounding red nodes such as “doh (2010)”, “le (2022)”, “cantele (2018)”, “buallay (2020)”, “sardana (2020)”, “tien (2020)”, “grekova (2016)”, and “gupta (2020)”. At the lower left and lower right edges, yellow nodes appear and are labeled “revelli (2015)”, “von wallis (2015)”, “velte (2017)”, “min (2017)”, “lu (2018)”, “velte (2020)”, and “patara (2020)”.Bibliographic coupling of documents highlighting research linkages
