私は強制的なグラフを作成しようとしていますが、リンクが湾曲しています。誰もそれを直線に変える方法を知っていますか？曲線を直線に変更する

可能な重複：ストレートラインリンクのための曲線の代わりに（しかし、いくつかのリンクのみ）]（http://stackoverflow.com/questions/28098879/d3-force-layout-straight-line-instead-of-curve-for-links-but-only- for-some-lin） –
重複した投稿をチェックし、アドバイスに従ってください（ 'linkArc（d）'に 'dr = 0'を設定し、jsBinでテストすると直線になります）。 –
