The error message "echarts is not defined" usually indicates that the ECharts library is not properly loaded on the web page. Here are some possible solutions:
1. Make sure that you have included the ECharts library in your HTML file using a script tag. For example:
```html
<script src="https://cdn.jsdelivr.net/npm/echarts/dist/echarts.min.js"></script>
```
2. Check that the path to the ECharts library is correct. Ensure that the URL is valid and that the file exists on the server.
3. If you are using a module bundler like Webpack or Rollup, make sure that you have installed the ECharts library and imported it correctly in your JavaScript code.
4. Verify that the ECharts library is loaded before your JavaScript code runs. You can do this by placing your code in a callback function that is executed when the document is ready, or by using the `defer` attribute on the script tag.
If none of these solutions work, please provide more information about your code and how you are using ECharts, so that I can assist you further.
