VOSviewer is a free software for creating and viewing bibliometric maps. Unlike other programs, it focuses on the graphical representation of these maps, making them easier to interpret. The software can handle large maps, such as a co-citation map of 5,000 major scientific journals. It offers various views, including label view, density view, cluster density view, and scatter view, each emphasizing different aspects of the map. VOSviewer also includes zoom, scroll, and search functions, which are useful for examining large maps. The software uses the VOS mapping technique, which is effective for creating structured maps. It can also display maps created with other techniques like multidimensional scaling. VOSviewer is available on multiple platforms and is freely accessible. The paper discusses the functionality, technical implementation, and application of VOSviewer in creating and interpreting bibliometric maps. It also compares VOSviewer with other software like SPSS and Pajek, highlighting its advantages in handling large and complex maps. The software is particularly useful for visualizing clusters and relationships in large datasets.VOSviewer is a free software for creating and viewing bibliometric maps.
