Complete graph creator

This one is very similar to A Simple Gravity Model except that this one is made with javascript (Raphael.js)  and does not has the gravity model for the width of the links. I made this as a demonstration for how easy it is to make interactive graphics with javascript. With less than 40 lines of code, with raphael and javascript we can create this complete graph generator where you can click the canvas to create nodes and click and drag the nodes to move them. the links are generated and updated based on the position of the nodes. I am planning to create a full suite of tools for making and analysing networks online for which this is the first step. [ link: ]


var paper = Raphael(0,0,'100%','100%');
var background = paper.rect(0,0,'100%','100%').attr({'fill':'#ddd','stroke-width':'0'});
var circles = [];
var lines = [];{
	circles.push(new circle(event.clientX,event.clientY));
function refreshLines(arr) {
	for (i in lines) {
	for (i in arr) {
		for (j in arr) {
			lines.push(new line(arr[i],arr[i],arr[j],arr[j];
function circle (mx,my) {
			var color = this.attrs.fill=="#444" ? '#f00' : '#444';
			var color = this.attrs.fill=="#444"; ? '#f00' : '#444';
function line (sx,sy,ex,ey) {
	return  paper.path( "M"+sx+","+sy+" "+"L"+ex+","+ey ).attr({stroke:'#444'});
