本画板在WPF-Diagram-Designer的基础上进行的开发，界面框架使用Fluent.Ribbon的框架。

先上源码地址：https://gitee.com/akwkevin/aistudio.-wpf.-diagram

2023年2月5号更新内容：

本次更新主要参照了一个Blazor的Diagram的画线算法，链接地址:https://github.com/Blazor-Diagrams/Blazor.Diagrams,感谢作者。

1.连线改进，新增连线算法，目前共4种连线：Smooth（曲线），Straight（直线），Boundary（网格边界连接模式），Corner（折线）

2.序列化改进，xml与json序列化，新增自定义元素后，无需更改根元素，只需要在新增的元素上添加序列化的对象即可，扩展性更灵活了。

3.箭头改进，箭头按照连线的实际角度显示（即0-360度），还支持自定义的箭头path。

4.新增快捷键自定义扩展，用户可根据自己的习惯定义快捷键。

5.封装了一个标准的工作流控件FlowchartEditor，具体使用可以参照开源权限管理框架种的用法： https://gitee.com/akwkevin/aistudio.-wpf.-aclient

nuget地址：

6.连接上添加动画：路径动画效果和线条流动效果。

7.改变结构，使用户更容易自定义自己的样式，覆盖系统默认样式。

8.从Blazor.Diagrams种引入PortlessLinks（直接连接两个node，不需要port），自动连接节点Snapping，按距离最近连接ReconnectLinksToClosestPorts

9.新增Demo示例，帮助用户快速上手，见底部2023年2月5号更新附加说明。
