Nets

Nets is a visualization library for drawing network graphs, based on matplotlib

依赖

python >= 3.12
matplotlib

使用

下载：https://github.com/PythonnotJava/Nets/releases/tag/V0.1.0

然后：pip install Nets-0.1.0-py3-none-any.whl

计划开发

• 样图（长度可能是假的，只是为了呈现图像效果）
• 实际比例图（遵循严格的计算，按比例缩放到图中）

注意事项

• Nets的图元布置时，某些图元可以获取在画布上相对与另一图元的真实长度；但同时也可以在场景有限的前提下，随意设置长度，特地提醒
• 图元所有具备的属性，都是真实数据
