add ( graph statement -- graph' )
Graphviz » Graphviz data structures

Prev:	<edge> ( tail head -- edge )
Next:	add-node ( graph id -- graph' )

Vocabulary
graphviz

Inputs

graph	a graph or a subgraph
statement	an object

Outputs

graph'

a graph or a subgraph

Word description
Adds an arbitrary object to the statements slot of a graph or subgraph, leaving the updated tuple on the stack. This is the most basic way to construct a graph.

Notes
add does not check the type of statement. You should ensure that graphs and subgraphs only contain instances of:

•	subgraph
•	node
•	edge
•	graph-attributes
•	node-attributes
•	edge-attributes

Examples

USING: accessors graphviz prettyprint sequences ; <graph> 1 <node> add statements>> [ id>> . ] each
"1"

USING: accessors graphviz prettyprint sequences ; <graph> 1 <node> add 2 <node> add statements>> [ id>> . ] each
"1" "2"

USING: accessors classes graphviz prettyprint sequences ; <graph> 1 <node> add 2 <node> add 1 2 <edge> add statements>> [ class-of . ] each
node node edge
