The network consists of nodes represented by circles connected by curved lines. Circles are colored into three groups: red, blue, and green. Each circle is labeled with an author’s name and publication year. The colored clusters represent citation or co-authorship connections: the red cluster is positioned at the center, the blue cluster at the bottom left, and the green cluster on the right, with multiple linking lines connecting nodes across clusters. The red cluster includes the nodes: “parchman ml, 2011”, “huang k, 2008”, “provan kg, 2012”, “morrissey jp, 2002”, “bazzoli gj, 1998”, and “martin gp, 2009”. The blue cluster includes the nodes: “lorant v, 2019”, “fleury mj, 2006”, and “vargas i, 2015”. Note: several unlabeled blue nodes are also shown within this cluster. The green cluster includes the nodes: “de stampa, 2009”, “tzannis a, 2013”, “black hg, 2015”, “sudbury-riley l, 2021”, “beirão g, 2017”, “godinho ma, 2020”, “janse van, 2018”, “barrett d, 2014”, and “eriksson e, 2020”.
