怎样画卡诺图

为了完成作业，我必须附上一张卡诺图。该图如下所示：

我对 LaTeX 还很陌生，真的不知道该怎么做。我知道如何制作表格等，但经过几个小时的寻找，我还是想不出一个相对简单的方法来制作圆圈。我找到的最接近的方法是：http://www.ctan.org/tex-archive/macros/latex/contrib/karnaugh，至少它们的名字相同，但地图看起来与我的地图看起来非常不同。我意识到我应该尝试解决它，但我真的不知道。

我稍微修改了给出的答案伊格纳西这里：

看起来更像您想要的。查看karnaugh该答案中定义的环境与此处修改后的版本之间的差异，以了解如何进行更改。 如果您发现这个答案有用，请赞成上面链接的答案，而不是这个。 我个人完全不知道，TikZ所以很遗憾我无法给你提供更多帮助。
