This visualisation shows a network representation of the connections between the main fields of research covered by Danish publications (showing by default the top 1000 connections between topics).
Each node in the network represents one field of research at either the top or second level of the classification system (a publication can be categorised under one or more "Fields of Research (FOR)"). Each connection between two nodes represents one or more instances of those fields of research co-occurring on one or more publications. The size of the node represents the number of publications connected to that field of research. The "thickness" of the connection represents the number of publications in which those two fields of research co-occurred. Fields of research that are closer to each other in the graph tend to have more connections with each other than groups of fields of research that are further apart.
