 当前结构问题：随着功能的增加，代码可能会变得臃肿，难以管理。
优化建议：可以将相关的功能进行模块化拆分，例如将与圆的绘制逻辑相关的代码提取到一个独立的类中，将与坐标范围处理相关的代码提取到另一个类中。这样可以提高代码的可读性和可维护性。
MVVM 模式的应用
优势：
分离关注点：MVVM 模式将应用程序分为三个主要部分，即模型（Model）、视图（View）和视图模型（ViewModel）。模型负责处理数据和业务逻辑，视图负责展示用户界面，视图模型作为中间桥梁，连接模型和视图，负责处理视图的交互和数据绑定。这样可以使代码的各个部分职责更加明确，便于开发、测试和维护。
提高可测试性：由于视图模型不依赖于具体的视图，因此可以更容易地对其进行单元测试。可以通过模拟视图模型的依赖项来测试其业务逻辑，而无需依赖于 UI 界面。
数据绑定和交互：MVVM 模式利用数据绑定技术，使得视图和视图模型之间的数据交互更加便捷和直观。当视图模型中的数据发生变化时，视图会自动更新；反之，当用户在视图中进行操作时，也会自动更新视图模型中的数据。
