<p>PROBLEM TO BE SOLVED: To provide a technique for visualizing a graph, capable of obtaining graph visualization display satisfying non-overlapping of nodes and neighboring arrangement of relevant nodes to streaming data having continuous variation of a data structure, such as variation of a node number or an edge number with optimal arrangement at a high speed in real time.SOLUTION: The display device for visualizing a graph comprises: arrangement change means for moving the sum of moving distances obtained by moving the existing nodes of both ends to be approached or to be separated when a new edge is added between two nodes already arranged on a display space of display means, as a range of a specified value to change arrangement of the nodes; and thereafter, added node arrangement determination means for arranging an added node and node arrangement coordinate optimization update means for applying a predetermined dynamic model to all nodes to correct the position of each node.</p> |
