Here is the Graphviz code, to compare (I also attached the automatically produced PNG but Graphviz can make PDF or SVG as well): // See http://www1.ietf.org/mail-archive/web/ietf/current/msg39858.html digraph bryantnetwork { label = "Stewart Bryant's network"; // Routers node [shape=box, fontsize=15]; // Links edge [len=2.0]; A -> B [label="2"]; A -> D [label="4"]; B -> A [label="6"]; B -> C [label="10"]; C -> B [label="9"]; C -> D [label="8"]; D -> A [label="16"]; D -> C [label="99"]; }
