a network visualization that shows the flow of knowledge between scientific fields based on the weighting of citations by subject field. a static map represents between fields. the dataset is based on Thomson Scientific's 2004 Journal Citation Reports (JCR), consisting of 6,434,916 citations from 6128 journals.
orange circles represent fields, with larger, darker circles indicating larger field size as measured by eigenfactor. blue arrows represent citation flow between fields. an arrow from field A to field B indicates citation traffic from A to B, with larger, darker arrows indicating higher citation volume
