这是一个建立在D3顶层的库，旨在改进我们处理大型杂乱图形的方式。它扩展了节点和链接与节点组的概念。当多个节点实际上是同一个节点或属于同一个组时，这很有用。 

数据模型

最简单的方法是ggraph.convert使用有效的D3对象调用： 

var graph = {
  nodes:[
    {id: "Maria West", type: "female"},
    {id: "Hazel Santiago", type: "male"},
    {id: "Sheldon Roy", type: "male"}    
  ],
  links: [
    {source: "Maria West", target: "Hazel Santiago", value:100},
    {source: "Maria West", target: "Sheldon Roy"}    
  ]
}

converted = ggraph.convert(graph);

用法

初始化：

ggraph.init('container', 25); // Marker timeout
ggraph.draw(converted);

将节点合并到组中：

// Merge selected
ggraph.merge(selection.all());

// Into single group
ggraph.merge(['Maria West', 'Sheldon Roy']);

// Into several groups
ggraph.merge([
  ['A', 'B'],
  ['C', 'D']
]);

拆分并删除：

ggraph.split(['Maria West', 'Sheldon Roy']);
ggraph.remove(['Maria West', 'Hazel Santiago']);
