<canvas id="mycanvas" width="550" height="400"></canvas> <script>     var randomcolour;     var randomsize;     var xpos;     var ypos;     var i;     var j;      randomcolour = '#' + math.random().tostring(16).substring(4); // random colour     c = document.getelementbyid("mycanvas");     ctx = c.getcontext("2d");      function drawfilledcircle(size,xpos,ypos,colour){    //draw circle         ctx.beginpath();         ctx.arc(xpos,ypos,size,0,2*math.pi);         ctx.fillstyle = colour;         ctx.fill();     }      function drawsplatter(size,xpos,ypos,colour){       // draw splattered circle         for(j=0;j<10;j++){             var splatsize = size / math.round(math.random()*30);             drawfilledcircle(splatsize,xpos + math.round(math.random()*50),ypos + math.round(math.random()*50),colour);         }     }   </script> 

var randomcolour;  var randomsize;  var xpos;  var ypos;  var i;  var j;    c = document.getelementbyid("mycanvas");  ctx = c.getcontext("2d");    function drawfilledcircle(size, xpos, ypos, colour) { //draw circle    ctx.beginpath();    ctx.arc(xpos, ypos, size, 0, 2 * math.pi);    ctx.fillstyle = colour;    ctx.fill();  }    function drawsplatter(size, xpos, ypos, colour) { // draw splattered circle    (j = 0; j < 10; j++) {      var splatsize = size / math.round(math.random() * 30);      drawfilledcircle(splatsize, xpos + math.round(math.random() * 50), ypos + math.round(math.random() * 50), colour);    }  }    var maxsize = 30;  var minsize = 10;  var maxx = c.width;  var maxy = c.height;    function randoms() {    var size = math.ceil(math.random() * maxsize);    size = math.max(size, minsize);    var x = math.floor(math.random() * maxx);    var y = math.floor(math.random() * maxy);    var colour = '#' + math.random().tostring(16).substr(2,6);    return {size:size, x:x, y:y, colour:colour};  }    (var = 0; < 10; i++) {    var r = randoms();    drawfilledcircle(r.size, r.x, r.y, r.colour);    r = randoms();    drawsplatter(r.size, r.x, r.y, r.colour);  }
