When an element is interactively arranged in cooperative with an input device and a display device, if the arranged element is overlapped with a line segment which connects the already arranged two elements to each other, the relation is provided among these three elements, to be displayed, so that the arranged element is interrupted in the relation between the already arranged two elements, which is specified by the line segment. Therefore, it becomes possible to interrupt the element in the relation which relates the already arranged two elements to each other. Hence, it is possible to easily provide the relation between elements while reflecting the intention of user as much as possible.
