“…The retrieved metadata from WoS was analyzed in R version 4.0.1 along with Rstudio Version 1.3.959 using bibliometrics R-package, where biblioshiny tool was used for analysis such as trend topics, thematic evolution, and multiple country publication (MCP) in the present study (Aria and Cuccurullo, 2017). In thematic evolution, strong centrality and high-density themes (upper-right quadrant) are known as motor themes (well developed and vital), weak centrality and high-density themes (upper-left quadrant) are known as niche themes (highly developed and isolated themes), low-density and weak centrality themes (lower-left quadrant) are known as marginal themes (emerging or declining themes), and strong centrality and low-density themes (lower-right quadrant) are known as essential, but not developed, themes (basic and transversal themes) (Sharafuddin and Madhavan, 2020).…”
