关于echarts的问题，如何让关系图绕着一个点成圆弧形散开？

现在的配置渲染效果入下

想大致做成这个效果

配置代码入下

datas = [
            {
                nodes:[
                    {id:0},
                    {id:1},
                    {id:2},
                    {id:3},
                    {id:4},
                    {id:5},
                    {id:6},
                    {id:7},
                    {id:8},
                    {id:9},
                    {id:10},
                    {id:11},
