d3.js - 可折叠径向树 D3.js v5

Question

我正在尝试在 d3.js v5 中使用可折叠的径向树。v3 有很多示例，但我似乎找不到 v5 的任何可靠内容。我找到了这个示例d3.js v3 径向树，发现它与 v5 不兼容。：

var diagonal = d3.svg.diagonal.radial()
    .projection(function(d) { console.log(d);return [d.y, d.x / 180 * Math.PI]; }); 

我知道使用linkRadial为 d3.svg.diagonal 建议了替代方案，但这似乎也不起作用。我在控制台上没有收到任何错误，但我得到一个空格。但是，当我检查元素时，我确实在 DOM 中看到了它。

谁能指出我 v5 中的可折叠径向树？
