PURPOSE:To dynamically display the graphic such as a data flow chart written in a stage that details of the specifications are not determined yet by moving the graphic in accordance therewith in the case it is decided that how to move can be determined by only information of the graphic by a rule, and moving it by an operator's instruction in the case it is judged that the how to move cannot be determined. CONSTITUTION:In the case of displaying dynamically a data flow chart, how to move it is determined as automatically as possible in accordance with a specific rule, and only the part whose automatic determination is difficult is determined by an operator's instructed, by which the definition of the sequence and the dynamic display are executed, while reducing the trouble of an operator's input. In such a way, it becomes unnecessary to define a flow of data on the data flow chart extending over all, and by only the minimum input, the data flow chart can be displayed dynamically.
