推荐答案

这是问题所在:您无法做到.没有人可以，因为所谓的家谱"不是一棵树.根据定义，树是没有循环的图.一个家庭关系图的确有一个简单的原因存在循环:每个人都有父亲和母亲，并且在一棵树中，一个音符只有一个父节点".

因此，不存在家谱"之类的东西.没有人能创造出不存在的东西. :-)

我有一个意见，为什么这个东西仍然被称为家谱".我认为这个概念是在不计女性的情况下创建的，因此它实际上是一棵树，只显示父系线条.但是不确定，可能是我对这种现象的历史了解不足.

现在的问题是:如何创建族图?这将是一项艰巨的工作，需要彻底的设计和大量的时间.我可以看到这里要使用的两个基本功能:

Here is the problem: you cannot do it. Nobody can, because what is called a "family tree" is not a tree. A tree is by definition a graph without loops. A family relationship graph does have loops by a simple reason: everyone has both father and mother, and in a tree, a note only has a "parent node".

So, there is no such thing as "family tree". Nobody can create something which cannot exist. :-)

I have an opinion why this thing is still called "family tree". I think the concept was created when females was not counted, so it was really a tree, with only paternal lines shown. Not sure though, may be my knowledge of history of this phenomena is poor.

Now, the question is: how to create a family graph? This would be quite a job which needs thorough design and considerable time. I can see two basic features to be used here:
