var paper = Raphael( "holder", 400, 400 )
var circle = paper.circle(200, 200, 150) // 从200,200 开始画一个半径150的圆
circle.attr("fill", "#f00") //并用红色填充

下面的数字其实是一个小列表ul li,你可以把li设置出边框 设置border-radius属性为50%,就能实现圆圈效果了.
<ul><li>1</li>
<li>2</li>
<li>3</li>
</ul>
<style>
li{border:solid 1px purpleborder-radius:50%magin-right:10px }
</style>
//即可实现数字边框变成圆形
给你写了个Demo，你自己换成图片即可，但需要HTML5的支持。
