graphviz：左/右对齐节点而不是居中？

Question

有没有办法让graphviz左对齐或右对齐同一级别的节点，而不是居中？

   digraph h {
     rankdir=LR;

     node [shape=record,height=.08,fontsize=11];

     elk[label="elk|I am an American Elk"];

     buffalo[label="buffalo|Just a buffalo|everywhere I go|people know the part I'm playing"];

     cow[label="cow|moo"];

     moose[label="Bullwinkle J. Moose|Hey Rocky, watch me pull a rabbit out of my hat!"];

     zoo [label="zoo|<p0>|<p1>|<p2>|<p3>"];

     zoo:p0 -> elk;
     zoo:p1 -> cow;
     zoo:p2 -> moose;
     zoo:p3 -> buffalo;
   }

Answer 1

很高兴看到有人使用如此重要的数据。

这是一种无法满足的方式：

digraph h {
     rankdir=LR;
     node [shape=record,height=.08,fontsize=11];
     zoo [label="zoo|<p0>|<p1>|<p2>|<p3>"];

     node [width=3.5];
     elk[label="elk\l|I am an American Elk\l",];
     buffalo[label="buffalo\l|Just a buffalo\l|everywhere I go\l|people know the part I'm playing\l"];
     cow[label="cow\l|moo\l"];
     moose[label="Bullwinkle J. Moose\l|Hey Rocky, watch me pull a rabbit out of my hat!\l"];

     zoo:p0->elk; zoo:p1 -> cow; zoo:p2 -> moose; zoo:p3 -> buffalo;
}

为该等级中的每个框赋予相同（经验确定的）宽度，然后使用奇怪的\l“左对齐的换行符”左对齐文本。
