Vocabulary

graphviz

Inputs

None

Outputs

Word description

Constructs an empty, strict, directed graph.

Notes

Because it's rare for graph id s to be meaningful or useful, <strict-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,

In strict graph s, there is at most one edge between any two node s, so duplicates are ignored by Graphviz.
