Here's all you have to do to add clustering to your node.js application.

save this code as cluster.js, and run cluster.js instead of server.js (or /bin/www, or whatever it's called for your project)
the only line you'll need to change is the last line - it needs to point to the location of your server.js file

var cluster = require('cluster');

if (cluster.isMaster) {
  // Count the machine's CPUs
 var cpuCount = require('os').cpus().length;

	angular.module('d3AngularApp', ['d3'])
	.directive('d3Bars', ['$window', '$timeout', 'd3Service',
	function($window, $timeout, d3Service) {
	return {
	restrict: 'A',
	scope: {
	data: '=',
	label: '@',
	onClick: '&'
	},
