VOSViewer is an open-source tool for creating visualizations of bibliometric networks. You can create maps of the connections between journals, researchers, or individual publications based on citations, co-citations, co-authorship, and more. VOSViewer also has some limited text mining functionality. One great advantage is the ability to import data downloaded directly from Web of Science, Scopus, PubMed, or WikiData. The visualizations resemble heat or cluster maps. VOSViewer is a powerful tool but can be intimidating for beginners to get comfortable with – for help, contact the Oxford College Library!
