![Tikz 中的美国阿比林拓扑:如何进一步改善图片](https://linux22.com/image/342648/Tikz%20%E4%B8%AD%E7%9A%84%E7%BE%8E%E5%9B%BD%E9%98%BF%E6%AF%94%E6%9E%97%E6%8B%93%E6%89%91%EF%BC%9A%E5%A6%82%E4%BD%95%E8%BF%9B%E4%B8%80%E6%AD%A5%E6%94%B9%E5%96%84%E5%9B%BE%E7%89%87.png)
受 Botoeva 的 kb-exchange 图的启发,我在 TikZ 中复制了美国阿比林拓扑。以下是示例的代码。但是,我想在平面上呈现此拓扑的三维视图,这是我向此论坛寻求帮助的原因之一。此外,我还想听听关于如何进一步改善图片等的建议,我不得不承认,在 TikZ 方面我还是个初学者
