在业务开发中需要绘制数据流向图，由于echarts关系图的限制以及需求的特殊要求，转而使用antv/g6实现，本文以代码的方式实现数据流向需求以及节点分组,版本"@antv/g6": "^4.8.24",
本文主要列出关键性的代码，并非全部代码
静态数据如下
tsgetCenterFlowG6ApiV2(data = {}) {
return new Promise((resolve) => {
let nodes: any = []
for (let i = 1; i <= 14; i++) {
let node: any = { id: "node-" + i, label: "node-" + i }
if (i % 3 === 0) {
node.class = "c0"
} else if (i % 3 === 1) {
node.class = "c1"
} else if (i % 3 === 2) {
node.class = "c2"
}
nodes.push(node)
