単純化されたネットワーク プロットを描画するために、フォース レイアウトを使用できると考えました。

別々のソースからさまざまなリンク距離を持つ同じターゲットを持つようにリンクを設定しましたが、プロットすると次のプロットが得られます。

ここに画像の説明を入力

プロットは技術的には正しいですが、左上の点を中央に配置し、他の点は中央から異なる長さで出ていきたいです。

これははるかに単純な視覚化であるため、強制レイアウトを使用すべきではありませんか? 間隔をあけるのに役立つので、フォースレイアウトが役立つと思っていましたが、十分に理解していないようです。

コードは次のとおりです。

問題は、リンク距離関数thisで、データ要素の代わりに使用していることですd。正しいコード:

var force = d3.layout.force()
  .nodes(nodes)
  .links(links)
  .linkDistance(function(d) { return d.value; })
  .size([width, height]);

私はあなたのコードでjsFiddleを書きました。結果は、多かれ少なかれ期待したものです。よろしく
