Inputs and outputs

graph

a graph

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

Notes
Because it's rare for graph ids to be meaningful or useful, <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,

<graph> "G" >>id
