GRAPH CREATION METHOD AND GRAPH CREATION DEVICE

A graph creation method includes setting on a plane a coordinate system in which three axis extend from an origin in a radial fashion, setting three evaluation results of three evaluation item for an evaluation object on each the three axis; determining a balance being one of center, circumcenter, incenter, orthocenter, and excenter of a polygon the vertices of which correspond to the three evaluation results set on the three axis; and creating on the coordinate system a graph in which the balance is set.
