private void init(Graph g, Rectangle2D b) {
initSchema(g.getNodes());
temp = b.getWidth() / 10;
forceConstant = 0.75 *
Math.sqrt(b.getHeight()*b.getWidth()/g.getNodeCount());
// initialize node positions
Iterator nodeIter = g.nodes();
Random rand = new Random(42); // get a deterministic layout result
double scaleW = ALPHA*b.getWidth()/2;
double scaleH = ALPHA*b.getHeight()/2;
while ( nodeIter.hasNext() ) {
NodeItem n = (NodeItem)nodeIter.next();
Params np = getParams(n);
np.loc[0] = b.getCenterX() + rand.nextDouble()*scaleW;
