想想好像好久没用写博客了！ 由于最近想跳槽了(ps:尽管公司挽留，提出一些异与往常的挽留“制度”，But确实已经死心了) ，发现前一段时间一些做Hadoop,和Spark同事时常来请教网络拓扑图的有关问题，由于当时确实比较忙，没时间帮着一起分析，表示歉意！
先前整理过份简单的Demo 但是不详细 基于Web实现在线绘画拓扑图[GraphEditor]
首先呢这里是要详述的几个要点：(我用图是直接显示了~) (当然这套UI模块是后期改动的~重点不在这里) [备案：后续使用文档]
显示拓扑图
其次呢是一些后期加上去的代码，我想既然用了网络拓扑图，后期的可塑性应该是很强的，部分都是后续需求加上去的！
言归正传，看完一些简单的流程图，我想都大概知道他的基本用途，和后期的塑造价值
一些简单的用途比如：做大数据Hadoop，Spark是的个个服务器之间的关系，以及关系流程图的描述； 大型企业的负载集群管理的关系以及流程图，安全管理，OA企业人士管理.....多事不可缺少的素材！
主要JQ代码模块：
上面的一些常量是一些属性！
