我正在尝试使用 Flare.json 数据，而无需手动调整 size 属性以获得令人愉悦的结果。理想情况下，我希望大小是嵌套深度的函数，因此在下图中，层次结构树上的节点将是它们所在节点的百分比。我正在使用以下示例：http ://bl.ocks.org/mbostock/4063530

同样，参考深度的能力将允许动态设置笔画宽度和字体大小。这将解决通过缩放容器而不是通过转换重绘来实现缩放功能时发生的问题。

在此处输入图像描述

以下是flare1000.json，其中所有大小都是相同的。我想那

我在 api 中没有找到对它的显式引用，但是有一个 d.depth 方法可以从根跟踪节点的深度。

我一直有类似的问题。具体来说，我正在使用的数据具有“大小”属性并没有真正意义，并且将其写入我可能想要显示的所有不同数据中不值得我花时间。要解决该问题，至少您需要查看以下代码：

var pack = d3.layout.pack()
    .size([diameter - 4, diameter - 4])
    .value(function(d) { return d.size; });

并用任何整数替换 d.size 。（我把它作为 Math.random() 的一个函数来获得任意大小的一些变化。）

至于深度，在对 API 和 d3.v3.js 进行了一些研究之后，在我看来，pack 布局默认不包含 d.depth 方法。这超出了我的编码技能水平，但假设您仍然在处理这个项目，您可能能够找出它包含的布局的深度是如何定义的并使用它。祝你好运！
