Word description Shorthand for <edge> to be used with ]; and attribute-setting generic words (see Notation for setting Graphviz attributes) so that setting an edge's attributes reads more like the equivalent in the DOT language.
Examples Instead of writing
<graph>
1 2 <edge> "red" =color add
it looks better to write
<graph>
1 2 [add-edge "red" =color ];
Compare this with the DOT language, where you'd write
graph {
1 -- 2 [ color="red" ];
}
This has the advantage over [-- and [-> of reading nicely for both directed and undirected graphs.
