D3强制定向图节点

问题描述：

我使用Force Directed Graph来构建一种流程图。它工作正常，除了节点没有特定的顺序。它们是随机的。我希望图表遵循层次结构的顺序。

I am using the Force Directed Graph to build a kind of flow diagram. It works fine except that the nodes have no specific order. They are random. I would like the graph to follow a hierarchical order.

var force = d3.layout.force()
    .nodes(d3.values(nodes))
    .links(links)
    .size([width, height])
    .linkDistance(90)
    .gravity(0.6)
    .charge(-2000)
    .linkStrength(0.3);

我想给节点一些

答

p>您可以使用强制布局与定量焦点，所以节点位于其数值层次结构。来自Mike的讲座（和验证码）的演示：

You can use the force layout with a quantitative foci so the nodes are located based in its numerical hierarchy. A demo from Mike's talk (and the code):
