At that time, a boundary icon 46 is displayed in a position wherein the node group 44 folded and not displayed must be displayed, a display mode of one non-display node selected as a representative node 48 among the nodes included in the node group 44 is changed from non-display to display, and screen display is performed.;COPYRIGHT: (C)2007,JPO&INPIT
