请问一下怎么实现图表的轮播，例如柱状图tooltip的轮播，饼状图条目选中的轮播？是否有计划将轮播作为功能选项开放出来？
这个功能算是一个比较常见的场景，开发者外部去做轮播效果考虑的东西比较多，而且需要对不同图表做不同处理
```

Start with the linked G2Plot CodeSandbox reproduction template and determine whether the request is for tooltip cycling, pie-item selection cycling, or both. No source file or test is named, and the issue does not define an API, supported chart types, or acceptance criteria, so the expected behavior must be clarified before implementation.
