The network displays multiple clusters of nodes, each represented by circles with labels, connected by thin lines indicating bibliographic coupling relationships, with labels adjacent to the nodes. At the lower left, a red cluster includes larger nodes labeled “chen (2008),” “chang (2011),” and “golicic (2013),” along with smaller connected nodes such as “yang (2018),” “kawai (2018),” “wong (2013),” “rehman (2021),” and “forsman (2013).” At the center, a yellow-green cluster includes nodes labeled “dangelico (2017a),” “li (2018),” “li (2020),” “arena (2018),” “sun (2019),” “pan (2020),” “qiu (2020),” and “aragon-correa (2016).” To the upper region, a purple cluster includes nodes labeled “pucci (2020),” “juntunen (2019),” and “gregory (2020).” To the right, a large green cluster contains nodes such as “dangelico (2017b),” “gerstlberger (2014),” “martinez-ros (2019),” “aldieri (2020),” “chiavresio (2015),” “corrocher (2017),” “garcia-sanchez (2020),” “christensen (2019),” and “orsatti (2020).” A smaller isolated green node labeled “barbier (2020)” appears toward the far right. In the lower right, a blue cluster includes nodes labeled “noci (1999)” and “mazzucato (2016),” with several linked nodes such as “bohnsack (2020),” “khurshied (2019),” and “hall (2019).” All clusters are interconnected through numerous fine lines indicating citation relationships among documents.Clusters based on the bibliographic coupling of documents.
