隐藏组织结构的第一个元素d3.js
Hide the first element of the organizational structure d3.js
我是d3 js的初学者，想对组织结构进行现代化改造，需要隐藏第一个结构元素，示例如图，代码摘自githubhttps://observablehq.com/@bumbeishvili/d3-v5-organization-chart
通过其 parent 属性隐藏顶部元素：
var nodeEnter = nodesSelection.enter().append('g')
.attr('class', 'node')
.style('visibility', d => d.parent ? 'visible' : 'hidden')
...
使用 depth 属性隐藏顶部元素的链接：
var linkEnter = linkSelection.enter()
.insert('path', "g")
.attr("class", "link")
.style('visibility', d => d.depth > 1 ? 'visible' : 'hidden')
...
