This is the screenshot of the chart demo: And the JSON schema is: ```json { "version": "sunmao/v1", "kind": "Application", "metadata": { "name": "Chart Application" }, "spec": { "components": [ {...

我觉得 default value 和 `exampleProperties` 不一定是可替代关系。 default value 可能用于某些场景下将属性处理为默认值，比如新增数组项、表达式转换为普通值等。 `exampleProperties` 可能用于新增组件时默认展示该组件的使用示例，可以和属性的默认值是不同的。
