VOSviewer constructs and visualizes bibliometric networks, including networks of terms found together in scientific literature. It supports networks based on citation, bibliographic coupling, co-citation and co-authorship, drawing on sources including Web of Science, Scopus, Dimensions, Lens, PubMed, Crossref, Europe PMC, OpenAlex, Semantic Scholar, OpenCitations and WikiData. Analysis tools include network layout and clustering, English-language text mining, fractional counting and thesaurus-based data cleaning. Visualizations include density and overlay views, with zooming and scrolling; high-resolution screenshots can be saved as bitmap or vector files. VOSviewer Online runs in a browser, opens JSON and map and network files, and shares visualizations through links, QR codes or embeddable HTML. The stand-alone version can share through Google Drive, Microsoft OneDrive and Dropbox. The software is available for Windows, macOS, Linux and the web; the download page also offers a JAR version for other systems. Running it requires Java 8 or higher. The maker describes its analyses as useful to research institutions and research funders. VOSviewer can be used freely for any purpose.
