nodes = [
        {
     "name": "结点1", "symbolSize": 10},
        {
     "name": "结点2", "symbolSize": 20},
        {
     "name": "结点3", "symbolSize": 30},
        {
     "name": "结点4", "symbolSize": 40},
        {

        {
     "name": "结点6", "symbolSize": 40},
        {

        {

]
links = []
for i in nodes:
    for j in nodes:
        links.append({
     "source": i.get("name"), "target": j.get("name")})
c = (
        Graph()
        .add("", nodes, links,repulsion=8000,layout='circular')#layout='force'或'circular'
        .set_global_opts(title_opts=opts.TitleOpts(title="Graph-基本示例"),)
)
c.render_notebook()

也可以用opts.GraphNode和opts.GraphLink设置点和线，这和使用 dict 类型效果是一致的。

        opts.GraphNode(name="结点2", symbol_size=20),
        opts.GraphNode(name="结点3", symbol_size=30),
        opts.GraphNode(name="结点4", symbol_size=40),
        opts.GraphNode(name="结点5", symbol_size=50),
    ]
links = [
        opts.GraphLink(source="结点1", target="结点2"),
        opts.GraphLink(source="结点2", target="结点3"),
        opts.GraphLink(source="结点3", target="结点4"),
        opts.GraphLink(source="结点4", target="结点5"),
        opts.GraphLink(source="结点5", target="结点1"),
