Vocabulary
graphviz

Inputs
None

Outputs

graph

a graph

Word description
Constructs an empty, non-strict, directed graph.

Notes
Because it's rare for graph id s to be meaningful or useful, <digraph> automatically generates one, just as in <anon>.

If you want, you can still give the resulting graph a specific id using standard words like >>id. For example,

<digraph> "G" >>id
