在我们能够把图形数据绘制到屏幕上之前必须首先将其转移到主浏览器进程这限制了我们能够采取的方法。
The image data must be transferred to the main browser process before it can be drawn to the screen, which limits the possible approaches we can take.
但正如您将在本文中看到的那样，还可以使用ming库用几乎与动态创建图片相同的方法来动态构建. swf文件，并在Web服务器上绘制图形。
But as you'll see in this article, you can also use the Ming library to build a.swf file dynamically in much the same way as you create an image dynamically to do graphing on your Web server.
如果您打算绘制大量节点(多于50个)，或者使用较大的Web页面缩略图呈现图形，确保使用千兆赫处理器和具有多个千兆字节的RAM。
If you intend to map a large number (more than 50) nodes, or rendering graphs with large Web-page thumbnails, make sure you have a gigahertz processor and multiple gigabytes of RAM.
