Question

我正在从模板制作树图。运行它所需的json是嵌套的，但也包含有关组级别的信息。我正试图弄清楚如何从json制作csv。我查了一下d3.nest但是这并没有在集团层面给你提供信息，所有的信息都留下了叶子。

新数据也更复杂（有8个级别，并非所有组都有子级），因此寻找一种解决方案，允许我递归地浏览数据并采用任何格式的嵌套。 See the csv data

我也考虑过使用python来解决这个问题，但是我对python的经验不足。

以下是json格式的示例，或此处为full file。

非常感谢任何指针或策略。

从

等数据开始

MSGraphSDK

并以

为目标

[
    {id: 1, title: 'hello', parent: 0},
    {id: 2, title: 'hello', parent: 0},
    {id: 3, title: 'hello', parent: 1},
    {id: 4, title: 'hello', parent: 3},
    {id: 5, title: 'hello', parent: 4},
    {id: 6, title: 'hello', parent: 4},
    {id: 7, title: 'hello', parent: 3},
    {id: 8, title: 'hello', parent: 2}
]

他使用此功能

[
    {id: 1, title: 'hello', parent: 0, children: [
        {id: 3, title: 'hello', parent: 1, children: [
            {id: 4, title: 'hello', parent: 3, children: [
                {id: 5, title: 'hello', parent: 4},
                {id: 6, title: 'hello', parent: 4}
            ]},
            {id: 7, title: 'hello', parent: 3}
        ]}
    ]},
    {id: 2, title: 'hello', parent: 0, children: [
        {id: 8, title: 'hello', parent: 2}
    ]}
]

我不得不重新调整我的数据并包含父ID，但这正是我所需要的。
