我是 D3 可视化的新鲜人。目前正在为数据沿袭创建 D3 树布局可视化。在数据沿袭流中，子节点可以从多个父节点派生。这是一个例子。在下面的示例中，“DevLead”可能与 2 名经理一起工作。
var data = [
{ "name": "Director", "parent": "null", "depth": 0 },
{ "name": "Manager1", "parent": "Director", "depth": 1 },
{ "name": "Manager2", "parent": "Director", "depth": 1 },
{ "name": "DevLead", "parent": "Manager1", "depth": 2 },
{ "name": "DevLead", "parent": "Manager2", "depth": 2 }
];
获取输出请参考下图。
我希望看到“DevLead”子项应该只显示一个，并且应该有来自“Manager1”和“Manager2”的派生。任何人都可以帮忙解决这个问题吗？
D3 树布局并不完全支持多个父级
你能做什么？
使用网络图代替 - 缺点是节点定位 难的
我有类似的要求并尝试构建类似的网络图
使用树形布局，但是当有很多节点时，它会变得混乱......
你可以检查一下
代码笔
在树布局上使用 hack - 从其他节点绘制附加链接
检查这个例子
另一个使用隐藏节点的黑客 -jsfiddle
另外，我认为这些链接将进一步帮助您：
d3.js 中的家谱
d-tree 库 - 具有多个父项的数据
如果您选择第一个选项，那么您可以通过删除和添加数据中的节点来使用此代码片段
