   Please put `echarts.init` inside `useEffect` or `useLayoutEffect`, render function may call multiple times so ur chart init again and again.
   
   ```js
   // pie.tsx
   useEffect(() => {
       if (pieRef.current) {
         waterChart = echarts.init(pieRef.current);
         waterChart.setOption(option);
       }
     }, [])
   ```
