1. A graphics image creation apparatus comprising:
- a sub-graph generator, for employing hierarchical graph data to generate a sub-graph comprising a graphics image that includes nodes and arcs for connecting said nodes, at a predetermined level; and
a sub-graph corrector, for, when said sub-graph generator has generated a sub-graph for a level lower than a predetermined node in said sub-graph that has already been generated, correcting the location of a node in said sub-graph that has already been generated.

Abstract
A graphics image for hierarchical graph data is generated in order beginning with the topmost level. When a sub-graph for a specific level is generated, and then a sub-graph for a lower level for a specific node in this sub-graph is generated, the size of the node for which the lower sub-graph is generated is changed so that the lower sub-graph is included in this node. Further, nodes near the node for which the size has been changed are moved, so that these nodes do not interfere with the sub-graph for the lower level.

4. A graphics image creation apparatus comprising:
-
a processor, for generating a graphics image that includes nodes and arcs for connecting said nodes, based on graph data; and
a display unit, for displaying said graphics image generated by said processor, wherein, when said processor generates a sub-graph that constitutes a graphics image for a predetermined level in hierarchical graph data, said processor changes the size of a node that corresponds to said sub-graph so as to include said sub-graph in said node, and moves a neighboring node of said node for which the size has been changed. - View Dependent Claims (5, 6, 7)

8. A graphics image creation apparatus comprising:
-
a processor, for generating a graphics image that includes nodes and arcs for connecting said nodes, based on graph data; and
a selected node receiver, for accepting a node that is selected to constitute a first graphics image that is generated by said processor, wherein, when graph data for a lower level exists for a node that is accepted by said selected node receiver, said processor generates a second graphics image based on said graph data for said lower level, and corrects said first graphics image.

9. A graphics image creation apparatus comprising:
-
a processor, for generating a graphics image that includes nodes and arcs for connecting said nodes, based on graph data; and
a selected node receiver, for accepting a node that is selected to constitute a graphics image that is generated by said processor, wherein, in a display space wherein a graphics image is displayed, said processor moves other displayed nodes away in directions opposite to those leading to a center point that corresponds to the coordinate values for a selected node that is accepted by said selected node receiver. - View Dependent Claims (10)
