D3.js高级节点连接(查找路径)

Question

我正在寻找建议或一些想法。我需要构建一些D3图表（看起来像组织图表），但具有一些高级功能。必须将某些节点与另一个带有路径连接的节点连接。看起来像屏幕截图1.应该分开这些行（每个连接 - 不同的行）。

我想做的是：为每个节点提供一定余地的其他点，并根据这些点（此处的可视化）构建一条路径，并为每条单独的行添加一些填充。

我不能选择其他类型的图表。

我当前的图形外观在这里：https：//blog.zubasoft.at/examples/d3.js/orgchart/

关于如何建立这种连接的任何想法？

Answer 1

我相信您将必须为每个连接创建一个路径。例如，在视觉上，您将连接5像素向右移动，然后将10个像素移至底部，然后向右移动直至到达目标节点的中心，然后向上移动。

如果您对节点有固定的垂直和水平边距，制定这些规则不会太糟糕。

Answer 2

您需要找到两行之间的交叉点，但是Formulla很复杂，请参见https://en.wikipedia.org/wiki/wiki/line–line_intersection>

您可以将演示波纹管用作起点
