Ggraph 是一个基于 D3 构建的复杂混合图形的库，它扩展了节点和链接的概念。非常适合一组或者多组节点连接的展示。
示例代码：
初始化:
ggraph.init('container'); ggraph.draw(converted);
合并节点到组中：
// Merge selected ggraph.merge(selection.all()); // Into single group ggraph.merge(['Maria West', 'Sheldon Roy']); // Into several groups ggraph.merge([ ['A', 'B'], ['C', 'D'] ]);
切分和删除：
ggraph.split(['Maria West', 'Sheldon Roy']); ggraph.remove(['Maria West', 'Hazel Santiago']);
