Re: [graphviz-interest] Meaning of "canon" output

The default output from dot is -Tdot, which is DOT syntax annotated with 
layout information.
With -Tcanon the layout is not done; the output is still in DOT syntax, 
but it
is just a canonically-formatted rewrite of the input.

$ echo "digraph  {hello->world}" | dot -Tdot
digraph {
     graph [bb="0,0,62.394,108"];
     node [label="\N"];
     hello     [height=0.5,
         pos="31.197,90",
         width=0.79437];
     world     [height=0.5,
         pos="31.197,18",
         width=0.86659];
     hello -> world     [pos="e,31.197,36.104 31.197,71.697 
31.197,63.983 31.197,54.712 31.197,46.112"];
}


$ echo "digraph  {hello->world}" | dot -Tcanon
digraph {
     node [label="\N"];
     hello -> world;
}
