一种新的层次信息可视化模型

随着信息的日益丰富和互联网技术的发展,如何在海量数据中获取有效信息这一问题促使信息可视化领域成为当前的研究热点之一。层次信息的可视化结构最直观的方式就是树型结构。但是传统的树型结构有一个很大的缺点:当结构的层次增多或者节点增多时,该结构需要占据大量的可视化空间。针对这个问题,在分析研究层次信息可视化技术的基础上,提出了一种新的层次信息可视化模型,即层次信息自由呈递模型。通过对多种关键特征的参数化,实现层次信息在任意方向上的自由呈递,以及Focus+context视图效果。

A New Model for Hierarchical Information Visualization

With the increasing information glut and the advances in data access on digital networks,the question on how to find specific information leads to information visualization as one of the hottest topics of significant development and research.Tree structure is the level of information visualization of the structure of the most intuitive way.But the traditional structure of the tree has a very significant drawback i.e.when the structure of the increase in the level of nodes or more,the structure of the need to take a lot of visual space.To solve this problem,in the analysis of the level of information visualization technology on the basis of this paper puts forward a new model of hierarchical information visualization,namely Free Display Model of Hierarchical Information.By parameterizing these key features,free display in any direction can be realized,and view of"Focus+Context"can also be realized relatively well.
