Graphviz notation » Aliases that resemble DOT code

Next:

-> ( graph tail head -- graph' )

Vocabulary
graphviz.notation

Inputs

graph	a graph or a subgraph
tail	an object
head	an object

Outputs

graph'

a graph or a subgraph

Word description
Shorthand for add-edge. Makes undirected graphs read more like graphs in the DOT language.

Examples
Instead of writing

<graph> 1 2 add-edge 3 4 add-edge 5 6 add-edge

it looks better to write

<graph> 1 2 -- 3 4 -- 5 6 --

Compare this with the DOT language, where you'd write

graph { 1 -- 2 3 -- 4 5 -- 6 }
