简单的跨浏览器绘制JavaScript库(Simple cross browser draw javascript library)

 我们正在构建一个Web应用程序库，需要绘制一些折线/多边形/圆/矩形。 
 
 我们也希望这些矢量可以编辑。 
 
 所以我想知道是否有一个跨浏览器绘图库可以导入我们的代码？ 
 
 我知道拉斐尔，但我觉得它太强了，我的意思是我们不需要太多的功能。 
 
 我们也发现了这一点 ，它使用div像素像素化渲染矢量。 但我们认为效果并不好。 
 
 有什么建议吗？ 

We are building a web app library which need draw some polyline/polygon/circle/rectange.
 
Also we want these vectors can be edited.
 
So I wonder if there is a cross browser draw library can be imported to our codes?
 
I know Raphael,however I think it is too strong,I mean there are too many features we do not need.
 
Also we found this,it render the vector using divs pixel by pixed. But we think the effect is not good.
 
Any suggestion?
