我想创建类似于以下的图表： http://www.texample.net/tikz/examples/marketing-distribution-channel/
相反，我希望底部的两个节点指向顶部节点，除非它们重叠，否则我无法让它们这样做。
另外，我想添加与链接中一样的文本，例如箭头旁边的链接中的测试参与率。但是，每次我添加文本时，节点都会向右移动太远，以至于有些节点不再显示在屏幕上。
我想做的另一件事是，在显示完所有节点后，我想添加一个新的框架标题。我原本以为只有或揭露可能会奏效，但似乎不行。我还想添加一些带项目符号的文本。然而，它似乎没有遵循相同的间距和字体。参见叠加层 5 与幻灯片 2。
如能得到任何帮助我将非常感激。

编辑：使用答案中的代码，其中一个节点中的长文本似乎仍然存在问题：
