在 Vue 3 项目中，直接搬运 Vue 2 代码不生效，主要原因有三点：生命周期钩子的变化、Ref 获取方式的变化、以及 全局变量挂载时机。

以下是针对 Vue 3 组合式 API (Composition API) 优化后的代码，建议直接替换：

核心修改说明：
ref 声明：Vue 3 需要使用 const chartDiv = ref(null) 来声明模板引用。

生命周期：mounted 变为 onMounted，beforeDestroy 变为 onBeforeUnmount。

挂载时机：确保在 import world.js 之前，window.echarts 已经被赋值，否则 world.js 执行时依然会因为找不到 echarts 而报错。
