摘要
针对力导引算法缺乏交互性、效率低、美观性不足,提出一种面向交互的渐进式图布局算法IIA(Interaction Oriented and Incremental Algorithm)。该算法先对一小部分图数据进行可视化,然后根据用户的选择从已可视化的部分渐进式扩展,再利用改进的算法对扩展部分进行可视化。实验结果表明:IIA算法不仅能与用户交互,而且提高了可视化的效率,在美观性上也有所改善。
Aiming at the force-directed algorithm lacking of interactivity and aesthetics and low efficiency,an interaction oriented and incremental algorithm for graph visualization is proposed. Firstly,the algorithm visualizes a small portion of the graph data,secondly,extends the visualized data by user＇s selection,and then draws the extended data with the new algorithm. The new algorithm can not only interact with users,but also improve the efficiency of visualization and the aesthetics.
