摘 要:复杂关系网络数据的可视分析多采用有向加权的节点- 连接图布局。由于节点间的连接关系为多属性数据,传统的布局绘制算法难以完整地呈现数据间的组织结构。本文通过对力导向物理学模型进行优化设计,结合多通道视觉编码设计,完成对复杂关系网络数据可视化的绘制。相比较传统的节点- 连接图布局,本算法在呈现多属性网络数据时具有更好的认知效能。

Abstract:Visual analysis of complex relational network data mostly uses directed weighted node-join graph layout. Because the connection relationship between nodes is multi-attribute data,the traditional layout rendering algorithm is difficult to fully present the organizational structure of data. By optimizing the force-directed physical model and combining with the design of multi-channel visual coding,this paper completes the visualization of complex relational network data. Compared with the traditional node-connection graph layout,the algorithm has better cognitive performance in presenting multi-attribute network data.
Keywords:visual analytics;complex relational network;FDLA(Force-Directed Layout Algorithms)
