| Abstract: |
| The analysis of characteristics of hierarchical information and the proper selection of visualization methods will not only have important effects on the visualization applications of complex information, but also meet users diversified needs for visualization. To study the methods and steps for orderly display of large scale hierarchical information on limited screens will help solving the problems of information search difficulties caused by the increase of information. According the structural characteristics of hierarchical information, visualization description can be represented with node／line diagrams and tree maps, and can be realized in the two steps of information layout design and viewport navigation. 5 figs. 13 refs. |
| 中文摘要: |
| 对层次信息的特性进行研究并选择合适的可视化方法不仅对复杂信息可视化应用设计有重要作用，而且能满足多种可视化用户的需求。研究大型层次化信息在有限屏幕上有序显示的方法和步骤，有助于解决信息量增加带来的信息查询困难问题。根据层次信息特有的结构特征，可视化描述可以通过节点连线图和矩形嵌套图来表示，并可通过相应的信息布局设计和视图导航的两个步骤来实现。图5。参考文献13。 |
