私はD3-visulizationのための新鮮な蜂です。現在、データ系統のD3ツリーレイアウトのビジュアライゼーションを作成しています。データ系列では、複数の親から子ノードを派生させることができます。ここに例があります。以下の例では、 'DevLead'は2人のマネージャーと連携して動作します。D3ツリーレイアウトの視覚化 - 複数の親を持つ子を継承します

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 } 
     ]; 

以下の画像を参照してください。

Output

私は「DevLead」子どもたちが一つだけを表示する必要があります見てみたいと思いますし、「マネージャ1」と「マネージャ2」からの派生があるはずです。いずれにせよこれを手伝ってもらえますか?

D3ツリーレイアウトが複数の親を完全にサポートしていない

何をすることができますか?

  1. 使用ネットワークグラフの代わりに - 欠点は、そのノードの位置は、私は同様の要件を持っていたし、ツリーのレイアウトと 類似した建物のネットワークグラフを試してみましたが、多くのノードがある場合、それは厄介取得 ハード

    です。 ...
    you can check it on codepen

  2. 使用は、ツリーのレイアウトをハック - 他のノードから追加のリンクを描く
    check this example

  3. 使用
  4. 別のハック隠れノード - またjsfiddle

は、私はこれらのリンクは、さらにあなたを助けるだろう、と思う:

あなたが最初のオプションで行けば210

、ここで、あなたは削除し、データ内のノードを追加することによって、このスニペットで遊ぶことができます
