What is VOSviewer?

VOSviewer is a freely available Software-Tool, which can be used to construct and visualize bibliometric networks. It was created by Need Jan van Eck and Ludo Waltman, researchers of Leiden University. VOSviewer generates whole networks on the basis of bibliometric data, which show the relationship of different parameters to one another. Those networks may include journals, researchers, or individual publications, and they can be constructed based on citation, bibliographic coupling, co-citation, or co-authorship relations.
