关系图里的layout为circular时，连线会重叠

[gitXiaoQing]

One-line summary [问题简述]

关系图里的layout为circular时，去掉data里的x、y坐标值，若有节点A→节点B，同时又节点B→节点A，这两条线会重叠

Version & Environment [版本及环境]

• ECharts version [ECharts 版本]:
  当前版本
• Browser version [浏览器类型和版本]:
  谷歌浏览器63.0.3239.108
• OS Version [操作系统类型和版本]:
  win10

Expected behaviour [期望结果]

当layout改成circular后，显示连线（从节点A→节点B，和从节点B→节点A）可以区分开。
