PURPOSE:To easily visually grasp the tree structure by displaying the inclusive relation of constitutive units as the inclusive relation of graphic elements expressing the constitutive units in one direction and displaying the hierarchical relation of constitutive units as the other arranging positions of graphic elements expressing the constitutive units. CONSTITUTION:By the instruction of an input means 12, a logical node selecting means 13 selects a logical node managed by a logical node managing means 11. A graphic node managing means 15 performs the data management of plotting for the sizes and arranging positions of graphic elements by making them correspond to the logical node managed by the logical node managing means 11. On the other hand, a document structure display means 16 is provided with a graphic element generating means 161 for deciding the sizes of graphic elements corresponding to the logical node and dispatching them to the graphic data managing means 15 and a position deciding means 162 for deciding the arranging positions of graphic elements corresponding to the logical node and dispatching them to the graphic data managing means 15 and further, the document structure with the logical node selected by the selecting means 13 as the root of the tree structure is displayed on a display means 14 while referring to the plotting data of graphic elements in the graphic data managing means 15. |
