### 🐛 Question description [Please make everyone to understand it]
官方例子https://g2plot-v1.antv.vision/zh/examples/advanced/connection 在实际运行中报错说StateManager找不到，请问这个是在哪个版本能运行呀？想看看这块源码

### 💻 Link to minimal reproduction
https://g2plot-v1.antv.vision/zh/examples/advanced/connection

### 🏞 Expected result

### 🚑 Any additional [like screenshots]

* **G2Plot Version**:
* **Platform**:

Start by running the linked official connection example and reproducing the missing StateManager error. Then inspect the example's documented version and related source entry points to determine whether it targets an older release. Done means the supported version or a required example correction is clearly identified and the example runs without that error.
