Inputs

Outputs

graph

a graph

Word description
Constructs an empty, strict, undirected graph.

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

<strict-digraph> "G" >>id

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