Review Comment:
Thanks for your contribution! But I think it's needed to get a better design
on the API naming and implementation.
For example, it looks good to me if we call it `teleport` and the
`customContainer` could be named by `container`. If no specified container, it
fallbacks to `api.getDom()`, that is, the chart container.
