D3树的初始数据无法正确可视化 [英] Initial Data for D3 Tree are not properly visualize
本文介绍了D3树的初始数据无法正确可视化的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我设法使用d3制作了一个自下而上的家谱，添加，删除都按原样进行，但是当我尝试加载嵌套子项比根子多于2或更多的初始数据时，可视化所述数据中断.
I managed to use d3 to make a bottom up family tree, the adding, deletion works fine as it is, but when i try to load initial data that have nested children to be more than 2 or more than the root, visualization of said data breaks.

如何获取初始化数据以可视化给定的多个嵌套 孩子们?我错过了什么才能使它正常工作?
How do i get the initialize data to visualize given multiple nested children? What did i missed in getting it to work?
当节点超过3个级别时，如何计算和设置节点之间的间隔?
我已经按照自己的想法完成了输入，更新和退出操作，从而使其可以添加，删除. JSFiddle仅适用于根数据，以及添加和删除.
I've done the enter,update and exit as it should i think, resulting it to works in adding,deleting. JSFiddle for only root data, with adding and deleting.
当我初始化一个有多个孩子的数据时，可视化开始中断，而不是最初显示所有关系，而是仅显示一个关系. 上述问题的小提琴.因此:
When i initiliaze the data with more than 1 children, the visualization started to breaks, instead of initially showing all the relationships it only shows one relationship. The fiddle of said problem. As such:
当它最初加载嵌套子数据时，我想要实现的是嵌套关系的可视化，因为上面的情况应该是:
What i wanted to achieve when it initially load with nested children data are the visualization of the nested relationships, as situation above it should be:

推荐答案
好吧，看来我只是未能为每个成员初始化id，因为生成节点的重要部分高度依赖于id(很好您可以将其更改为任何真正独特的内容.)
Okay, it seems that i just failed to initiate the id for each of the members, since the important part of generating the node is highly dependent on id(well u can change it to anything unique really).
node = node.data(tree.nodes(root), function(d) { return d.id; });
link = link.data(tree.links(nodes), function(d) { return d.source.id + "-" + d.target.id; });
加载可视化所需的初始数据必须具有以下ID:
The initial data needed to load the visualization must have id as such:
{
id:2,
patient_name: "Adam Father",
reference_id: "199210291",
relationship: "",
pc_id: "121292",
consanguineous_marriage: false,
children: [],
problems: [{
id: 0,
name: "cleft lip",
impact: "disease",
remarks: "Need constant monitoring."
},
{
id: 1,
name: "cleft palate",
impact: "carrier",
remarks: "Need constant monitoring."
}]
},{
id:3,
patient_name: "Adam Mother",
reference_id: "199210291",
relationship: "",
pc_id: "121292",
consanguineous_marriage: false,
children: [],
problems: [{
id: 0,
name: "cleft lip",
impact: "disease",
remarks: "Need constant monitoring."
},
{
id: 1,
name: "cleft palate",
impact: "carrier",
remarks: "Need constant monitoring."
}]
}
