一个简单的WEB流程图组件[demo]

我们常常要在web上显示流程图,网上比较难找,到处要收费,自己琢磨了一个,
比较简单,包括开始节点，结束结点，两种节点框图(节点、容器)和两种特殊线（跳线、返回线）,
使用xml文件或xml字串作为数据源，
没有多少需求分析,给有心人参考,也收集一些建议，源码过段时间整理再放上。

demo代码

效果图如下:


数据源说明：

Code
        Dictionary<string, string> dicMap = DrawCommon.GetMapXmlString(x, y, w, h, sbXmlString.ToString());
        foreach (string TaskCode in dicMap.Keys)
        {
            string[] arr = dicMap[TaskCode].ToString().Split('&');

            sbMap.Append("<area target=\"blank\" href=\"" + Request.ApplicationPath + "/Detail_workflow.aspx?TaskCode=" + TaskCode + "\" shape=\"rect\" coords=\"" + arr[0] + ", " + arr[1] + ", " + Convert.ToString(Convert.ToInt32(arr[0]) + Convert.ToInt32(arr[2])) + ", " + Convert.ToString(Convert.ToInt32(arr[1]) + Convert.ToInt32(arr[3])) + "\">");

        }
        

        sbMap.Append("</map>");
        divMap.InnerHtml = sbMap.ToString();
