The strategic diagram or thematic map utilizes two parameters, namely “centrality” and “density,” to depict the characteristics of themes in a two-dimensional space. Annual scientific output, methodology, authors, citations, and subject matter keywords are also explored. The research utilised Clarivate Analytics Web of Science as its data repository, and the R package bibliometrics was used to analyse and display its findings.
