问个 js 的问题，当删除一个点时，如何查找到所有与之相关联的节点与连接信息并删除

var nodes = [
    {id: 1001, label: "A"},
    {id: 1002, label: "B"},
    {id: 1003, label: "C"},
    {id: 1004, label: "D"},
    {id: 1005, label: "E"},
    {id: 1006, label: "F"},
    {id: 1007, label: "G"},
    {id: 1008, label: "H"},
    {id: 1009, label: "I"}
];
var edges = [
    {from:1002,to:1001,id:"10021001"},//B>A
    {from:1003,to:1002,id:"10031002"},//C>B
    {from:1004,to:1003,id:"10021001"},//D>C
    {from:1005,to:1003,id:"10021001"},//E>C
    {from:1006,to:1002,id:"10021001"},//F>B
    {from:1007,to:1004,id:"10021001"},//G>D
    {from:1008,to:1007,id:"10021001"},//H>G
    {from:1009,to:1007,id:"10021001"} //I>G
]

graph LR
B-->A
C-->B
F-->B
D-->C
E-->C
G-->D
H-->G
I-->G

当删除 D 时，G、H、I 及连接线都要清除，数据是这样的

var nodes = [
    {id: 1001, label: "A"},
    {id: 1002, label: "B"},
    {id: 1003, label: "C"},
    {id: 1005, label: "E"},
    {id: 1006, label: "F"}
];
var edges = [
    {from:1002,to:1001,id:"10021001"},//B>A
    {from:1003,to:1002,id:"10031002"},//C>B
    {from:1005,to:1003,id:"10021001"},//E>C
    {from:1006,to:1002,id:"10021001"}//F>B
]

graph LR
B-->A
C-->B
F-->B
E-->C
