我用dot生成以下 PDF ：
我的主要问题是即使打印在A3上，字符尺寸也太小。此外，图表似乎可以变得更紧凑。例如，左上角的蓝色、绿色和棕色节点的存在扩展了宽度，但我看不出为什么整个前两行不能向右移动，导致至少减少 20%的宽度。最后附上.gv文件。
由于我自动生成.gv文件，我只能修改所有节点和边的图形级属性或属性或更改点调用，但我无法微调坐标或特定节点。
您是否看到任何明显的方法可以让我获得更紧凑的布局以允许更大的字符大小？
我使用的调用是：
dot -Gsize="16.52,11.68" -Gratio="fill" -Glandscape=false -Gsplines=ortho -Tpdf graph.gv -o graph.gv.pdf
