<p>PURPOSE:To easily grasp node information and link information by stepwise changing a virtual plane describing and allocating information as a node. CONSTITUTION:The display request of a virtual plane from a user is analyzed by an input request processing part 12, the relevant node is retrieved from the node information preserved in a node/link information storage part 18 and displayed at a display part 16 by a display request processing part 17. Concerning the related node display request of the user, the link information in the storage part 18 is retrieved by a related node retrieval processing part 13, and a related node ID is provided. The display position of the virtual plane for displaying the related node is calculated from this ID. Concerning a stepwise display request, the display request is prepared according to a stepwise display preparation rule by a stepwise display request preparation part 14, the relevant node information in the storage part 18 is retrieved by the display request processing part 17, and they are stepwisely displayed at the display part 16.</p> |
