Sorry, due to too many Echarts properties, this will be a lot of work, and I will consider adding .d.ts in the future.

In addition, I recommend that you use the helper tool to convert options to components, which may be easier to develop.

抱歉，由于Echarts属性太多，这将是一个很大的工作量，未来我会考虑添加.d.ts。

另外，我建议您通过辅助工具来将options转换为组件，或许这样开发起来更便捷一些。
