When an element is interactively arranged in cooperative with an input device and a display device, if at least a part of the arranged element is overlapped with an already arranged element, the relation of the already arranged element is inherited and association is made between these elements to provide a relation therebetween, thereby displaying the relation. Therefore, it becomes possible to inherit the relation of the already arranged element with a simple operation. Thereby, it is possible to easily provide a relation between elements by associating the elements with one another while reflecting the intention of user as much as possible.
