GRAPH GENERATION DEVICE, GRAPH GENERATION METHOD, AND GRAPH GENERATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a graph generation device which, when the content of graph structure data is updated, can lay out common nodes in such a way that the same physical relationship of the graph as its physical relationship before the update results.;SOLUTION: A storage device 30 has first graph structure data and layout original data for the first graph structure data stored in it. Data update registration means 51 stores second graph structure data in the storage device 30 when the second graph structure data is inputted in which the content of the first graph structure data is updated. Layout position calculation means 52 specifies, when generating a graph for the second graph structure data, a common node that is written in common in the second graph structure data and in the first graph structure data corresponding thereto, and maintains, for each common node, the relative physical relationship defined by the layout original data for the first graph structure data, under which conditions the graph is laid out.;COPYRIGHT: (C)2016,JPO&INPIT
