d3js tree.nodes()不是函数 [英] d3js tree.nodes() is not a function

问题描述

虽然下面的代码在d3v3中可以找到，但在v4中却失败了.

While the below piece of code works find in d3v3, it fails in v4.

 var nodes = tree.nodes(root).reverse(),
      links = tree.links(nodes);

未捕获的TypeError:tree.nodes不是函数

Uncaught TypeError: tree.nodes is not a function

在v4中有什么替代方案?

What is the alternative for it in v4?

推荐答案

import { hierarchy, tree } from 'd3-hierarchy'

// create a hierarchy from the root
const treeRoot = hierarchy(root)
tree(treeRoot)
// nodes
const nodes = treeRoot.descendants()
// links
const links = treeRoot.links()
