// Add node (ID: Hello) var n1 = g.addNode( "Hello", {"color" : "blue"} ); n1.set( "style", "filled" );

// Add node (ID: World) g.addNode( "World" );

// Add edge between the two nodes var e = g.addEdge( n1, "World" ); e.set( "color", "red" );

// Print the dot script console.log( g.to_dot() );

// Set GraphViz path (if not in your path) g.setGraphVizPath( "/usr/local/bin" ); // Generate a PNG output g.output( "png", "test01.png" );
