如何在GGR图形中翻转x轴和y轴

第一个图像是图形的手绘（使用MS word）图像。第二个图像是尝试使用ggraph生成相同的图形

下面是我用来在给定节点边缘连接时自动绘制图形的代码（代码采用自）。我想移动ggraph的x轴和y轴，如手绘图（图1）所示。从上到下颠倒x轴编号，并将y轴移动到顶部。我该怎么做呢

    header = T) %>%
  rownames_to_column("name")

E <- matrix(c(0,    1,    0,    0,    0, 0, 0,

这个例子似乎需要一些修正：
g@JuliusVainora道歉。我现在已经修好了。这是将ID列添加到数据框V中。我删除了该部分。现在应该可以了。
