Hi, this is the strategy we adopted. I just want to know why you want the source and target is the same.

如果
想让桑基图links中source和target值相同 你可以从数据源下手 循环一下然后加上索引

links: [{
"source": "Venezuela",
"value": 3,
"target": "Bahamas"
}, {
"source": "Venezuela",
"value": 1,
"target": "Japan"
}, {
"source": "Iraq",
"value": 1,
"target": "Spain"
}, {
"source": "Iraq",
"value": 327,
"target": "India"
}, {
"source": "India",
"value": 32,
"target": "Iraq"
}]

这种，source!=target, 但是Iraq 和 India 是有循环的，这个也也会报错。
