javascript - 多级分层边缘捆绑

Question

我想实现多级分层边缘捆绑。我的意思是我想灌输径向树的行为，比如层次结构和边缘捆绑，就像在分层边缘捆绑中一样。

我知道我需要为此使用两个 d3.js 布局。我还需要相应地更改我的 json 数据集。

我的示例数据集仅适用于普通 d3.js HEB

[
{"name": "A", "imports": ["A1", "A2", "A3"]},                    
{"name": "B", "imports": ["B1", "B2", "B3"]},                   
{"name": "C", "imports": ["C1", "C2", "C3"]},                   
{"name": "Employees", "imports": ["Emp1", "Emp2", "Emp3"]},        
{"name": "A1", "imports": ["Emp1", "Emp2"]},   
{"name": "A2", "imports": ["Emp3", "Emp2"]}, 
{"name": "A3", "imports": ["Emp1", "Emp3"]},
{"name": "C1", "imports": ["Emp1", "Emp3"]},
{"name": "C2", "imports": ["Emp2", "Emp3"]},
{"name": "C3", "imports": ["Emp1", "Emp2"]},                             
{"name": "B1", "imports": ["Emp1", "Emp3"]},
{"name": "B2", "imports": ["Emp2", "Emp3"]},                                               
{"name": "B3", "imports": ["Emp1", "Emp2"]},                        
{"name": "Emp1", "imports": ["A1","A3","B1","B3","C1","C3"]},   
{"name": "Emp3", "imports": ["A3","A2","B2","B1","C2","C1"]},
{"name": "Emp2", "imports": ["A1","A2","B2","B3","C2","C3"]}
]

但是我想展示的关系是：

最高级别的 A、B 和 C

A 是 A1,A2,A3 的父级

B 是 B1、B2、B3 的父级，

A 是 A1,A2,A3 的父级

C 是 C1、C2、C3 的父级，

因此，A1,A2,A3,B1,B2,B3,C1,C2,C3 处于第二级

然后，我想通过边缘捆绑显示 Emp1、Emp2 和 Emp3 与 A1-C3 的关系，如上数据集所示。

我希望我对此很清楚。所以，请告诉我如何显示这种行为或关系，以及需要对数据集进行哪些适当的更改。

您的问题的一个近似解决方案是将您的 JSON 示例的以下改编版本保存在文本文件中（例如“test.json”）：

[
{"name": "A.A1", "imports": ["Emp.Emp1", "Emp.Emp2"]},   
{"name": "A.A2", "imports": ["Emp.Emp3", "Emp.Emp2"]}, 
{"name": "A.A3", "imports": ["Emp.Emp1", "Emp.Emp3"]},
{"name": "C.C1", "imports": ["Emp.Emp1", "Emp.Emp3"]},
{"name": "C.C2", "imports": ["Emp.Emp2", "Emp.Emp3"]},
{"name": "C.C3", "imports": ["Emp.Emp1", "Emp.Emp2"]},                             
{"name": "B.B1", "imports": ["Emp.Emp1", "Emp.Emp3"]},
{"name": "B.B2", "imports": ["Emp.Emp2", "Emp.Emp3"]},                                               
{"name": "B.B3", "imports": ["Emp.Emp1", "Emp.Emp2"]},                        
{"name": "Emp.Emp1", "imports": ["A.A1","A.A3","B.B1","B.B3","C.C1","C.C3"]},   
{"name": "Emp.Emp3", "imports": ["A.A3","A.A2","B.B2","B.B1","C.C2","C.C1"]},
{"name": "Emp.Emp2", "imports": ["A.A1","A.A2","B.B2","B.B3","C.C2","C.C3"]}
]

然后使用 R 使用edgebundleR包生成 D3 边束图：

install.packages("devtools")
devtools::install_github("garthtarr/edgebundleR")
setwd("path/to/dir/with/file")
edgebundle("test.json")

这是结果的屏幕截图：
