var graph:Graph = new Graph();
addChild(graph);

var n1:Node = graph.createNode(100,100); // create first node with x:100, y:100
var n2:Node = n1.add(200,200);  // add another node connected to the node

var n3:Node = graph.addNode(300,300); // create another node
n1.connect(n3); // then connect it to first node
