Complex network graph display method and device based on compression clustering algorithm

The invention discloses a complex network diagram display method and device based on a compression clustering algorithm, and the method comprises the steps: S1, analyzing entity relation data, and constructing a relation link between a starting point entity and a terminal point entity; s2, constructing maplt according to the relation link; the method comprises the following steps of: 1, int, AdJacentIdgt; the relation structure stores a precursor entity set and a subsequent entity set of each starting point entity and each terminal point entity, the int structure stores the starting point entities or the terminal point entities, and the AdjactId structure is a structural body # imgabs0 # and stores a precursor node set and a subsequent node set corresponding to the starting point entities or the terminal point entities; and S3, setting a query condition, traversing the relation structures meeting the query condition, merging the relation structures, and inputting the merged relation structures into a layout a
