function drawShape(){
// get the canvas element using the DOM
var canvas = document.getElementById('tutorial');

// Make sure we don't execute when canvas isn't supported

if (canvas.getContext){

// use getContext to use the canvas for drawing
var ctx = canvas.getContext('2d');

// Draw shapes
ctx.fillRect(25,25,100,100);
ctx.clearRect(45,45,60,60);
