       使用javascript绘制图形，在html5中可以用canvas，但目前浏览器支持不够，

而 jsDraw2D正是一个很好的解决方案

例子（摘自官网）：

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
        <title>Untitled Document</title>
		<script type="text/JavaScript" src="jsDraw2D.js"></script>
    </head>
    <body>
    	<div id="canvas" style="overflow:hidden;position:relative;width:600px;height:300px;"></div> 
         <script type="text/JavaScript">

    //Create jsGraphics object
    var gr = new jsGraphics(document.getElementById("canvas"));

    //Create jsColor object
    var col = new jsColor("red");

    //Create jsPen object
    var pen = new jsPen(col,1);

    //Draw a Line between 2 points
    var pt1 = new jsPoint(20,30);
    var pt2 = new jsPoint(120,230);
    gr.drawLine(pen,pt1,pt2);

    //Draw filled circle with pt1 as center point and radius 30. 
    gr.fillCircle(col,pt1,30);

    //You can also code with inline object instantiation like below
    gr.drawLine(pen,new jsPoint(40,10),new jsPoint(70,150)); 

</script>
    </body>
</html>

 

该类库兼容各个版本的浏览器，功能还算强大
