Include custom node attributes in plot

Question

I need to plot a DOT graph as SVG/PDF but would like to include the node attributes for each node. For example, on the plot:

strict digraph G {

  start -> a0;
  a0 -> a3;
  j0[name=asd, weight=2];
  a3 -> j0;
  j0 -> end;
}

how to include name and weight values under j0, like (e.g.):

strict digraph G {

  start -> a0;
  a0 -> a3;
  a3 -> "j0\nname=asd\nweight=2";
  "j0\nname=asd\nweight=2" -> end;
}

Answer 1

Insert all the node attributes and values into the label attribute (https://graphviz.org/docs/attrs/label/), instead of the node name.

strict digraph G {

  start -> a0;
  a0 -> a3;
  a3 -> j0
  j0 [label="j0\nname=asd\nweight=2"]
  j0-> end;
}
