Graphviz: Putting a Caption on a Node In Addition to a Label
Solution 1:
To place captions outside the node, you may use xlabel:
digraph g {
forcelabels=true;
a [label="Birth of George Washington", xlabel="See also: American Revolution"];
b [label="Main label", xlabel="Additional caption"];
a-> b;
}
forcelabels=true makes sure no xlabel is omitted.
A second option is to use HTML-like labels:
digraph g {
a[label=<Birth of George Washington<BR />
<FONT POINT-SIZE="10">See also: American Revolution</FONT>>];
}
