   gexf metadata description: 'A Web network'.
   

3. Add nodes

   graph := gexf graph.
   node1 := graph createNodeWithId: '0'.
   node1 label: 'Hello'.
   node2 := graph createNodeWithId: '2'.
   node2 label: 'World'.
   

4. Connect nodes

   node1 connectTo: node2.
   

5. Export file

    	    export: gexf ]
   

Full example to show dependencies of classes from Moose

classes := ((model allWithSubTypesOf: FamixJavaType)  select: [ :d | d isStub not and: [ d isAnonymousClass not ]  ]).

gexf := GEXF new.
gexf metadata creator: 'Gephi.org'.
gexf metadata description: 'my project'.

graph := gexf graph.

dicClassNode := classes collect: [ :class | 
	| node |
	node := graph createNode.
	node label: class mooseName.
	class -> node
	 ] as: Dictionary.

dicClassNode keysAndValuesDo: [ :class :node |
	(class query outgoing dependencies targetsAtScope: FamixTType) do: [ :dep |
		dicClassNode at: dep ifPresent: [ :aDepNode | node connectTo: aDepNode ]
		 ] 
	 ].
