SVG is a scalable vector graphics based on XML.There are many advantages of using to depict vector graphics such as platform-independent, expansibility, flexibility and saving bandwidth etc.ASP.NET application can dynamically add powerful and interactive SVG visual elements.On this basis, using Ajax and simulated real-time data display can solve problems such as large information, network congestion, browser frequently refresh the page waiting for data transmission etc.An example is verified and a good conclusion is gained.%SVG是一套基于XML的二维可缩放矢量图形规范.它描述的矢量图形有许多优势,如平台无关,可扩展性、灵活性强和节省带宽等.ASP.NET应用程序可以在服务器端动态添加强大、交互式的SVG可视化元素.在此基础上,使用AjaX和数据库技术模拟实时数据的显示,有效解决传统方式下实时数据发布所面临的信息量过大,网络拥塞,浏览器频繁刷新页面等待数据传输等诸多问题,最后给出实例加以验证,并得出在实时数据发布领域中SVG优于传统表示方式的结论.
