图模型是一种广泛使用的建模工具。图的可视化作为一种直观的图数据分析工具被广泛使用。图数据可视化中最关键的技术是图布局算法,但是目前并没有高效的并行图布局算法,因此目前对于海量图数据的可视化是一个挑战性问题。针对这一问题,在力导向布局算法基础上,忽略弱关联顶点间的斥力计算,提出了k-friend布局算法;并针对海量图数据设计了高效的并行图布局算法。在人工和实际数据集上的测试结果表明,在布局质量降低可容忍的情况下,该算法大幅度提升了布局的速度。
Graph models are modeling tools which are widely used.Data visualization techniques have been widely used as intuitive data analysis tools.Graph layout algorithm is the most critical technique of graph visualization
while there are no effective parallel graph layout algorithms.So to study on visualization of massive graph data is a challenging problem.Aiming at this problem
based on the force-directed layout algorithm and ignoring the repulsion force computation between weakly associated vertexes partially
a k-friend approximate layout algorithm was proposed
and an effective parallel layout algorithm was designed for massive graph data.The experimental results on artificial and real dataset show that the algorithms proposed greatly improve the layout speed.
