The network shows multiple clusters of labeled circular nodes connected by lines, representing authors. Near the upper left area, a red cluster contains larger nodes labeled “singh r k”, “mishra r”, and “mangla s k”, with smaller connected nodes labeled “kumar v”, “kumar s”, “daim t u”, “salik a”, and “kazancoglu y”. On the left side, a blue pair of nodes labeled “lee j” and “khan v m” are connected by a line. In the lower left area, a purple pair labeled “lim” and “yang d” are connected. Slightly right of them, a teal cluster includes “dogan e”, “chishty m z”, and “binsaeed r h” connected by lines. In the upper center area, a green pair labeled “casaka p” and “asif m” appear connected. On the upper right area, a yellow pair labeled “duan j” and “li a” are connected. Slightly below them, a pink pair labeled “adrijan m d” and “alifah s” appear connected. On the right side, an orange pair labeled “islam s” and “balasubramaniam s” are connected. In the lower center area, a peach pair labeled “hopkins j” and “sakurai m” appear connected. Near the bottom center, a brown cluster includes “jokar m r r a”, “basbous a”, and “khedrmafi m” connected by lines. On the lower right side, a green cluster includes “alladi d”, “jayaraman r”, and “antony j” connected by lines. Nearby, a grey pair labeled “he k” and “chen w” appear connected. Slightly above the center right, a pink pair labeled “dehdas s” and “kumar v p” appear connected. Near the bottom right area, a blue pair labeled “ermakova o” and “danilionis a” appear connected. In the lower left corner area, a grey pair labeled “chatterjee s” and “chaudhuri r” appear connected.Co-authorship network analysis. Source: Authors’ elaboration based on Bibliometrix software
