新版本可以通过API的方式使用么

- [ ] I have searched the [issues](https://github.com/antvis/f2/issues) of this repository and believe that this is not a duplicate.

### What problem does this feature solve?
使用类似于G2的chart().position()的API方式使用

### What does the proposed API look like?
使用类似于G2的chart().position()的API方式使用

Start by reviewing F2's current chart construction and API usage, then compare it with the requested G2-like chart().position() style. Define the intended API surface and affected entry points before implementation; done means the proposed usage is supported and covered by appropriate tests or examples.
