Abstract:

Aiming at the large number of large-scale network nodes and complex structure, the direct display of its visuali-zation overlaps and the hierarchical information is difficult to observe. This paper designs a network structure visualization system based on B/S framework. The system first transforms the network into point and edge data structures. Then it introduces network structure feature parameters and network topology partitioning algorithm to construct the network model. Finally, the visualization methods and interaction methods for different requirements are designed. According to the comparison with Gephi and case analysis, the system has the characteristics of flexible performance, simple deployment, easy expansion, and cross-platform.

Key words: data visualization, visual analysis, network visualization, B/S framework, interaction

摘要：

针对大规模网络节点数目庞大、结构复杂，直接对其可视化存在显示重叠、层次信息难以观察的问题，设计了一个基于B/S架构的网络结构可视化系统。该系统将网络转变为点、边的数据结构；引入网络结构特征参数和网络拓扑结构划分算法来构建网络模型；设计了针对不同需求的可视化方法和交互方式。根据与Gephi的比较和案例分析，表明系统具有表现方式灵活、部署简单、易扩展、跨平台等特点。
