今天看到这样一篇有趣的文章webpage as graphic (42 hits)．基本思想是：网站中的页面会有许多tag也就是我常说的标签，有人编写了一个程序将这些标签渲染成不同的图形结构．很有新意．如下图为google网站的tag 标签图．你也可以输入自已的网站，查看结果，但要求你必须装有java运行环境．

Everyday, we look at dozens of websites. The structure of these websites is defined in HTML, the lingua franca for publishing information on the web. Your browser’s job is to render the HTML according to the specs (most of the time, at least). You can look at the code behind any website by selecting the "View source" tab somewhere in your browser’s menu.
HTML consists of so-called tags, like the A tag for links, IMG tag for images and so on. Since tags are nested in other tags, they are arranged in a hierarchical manner, and that hierarchy can be represented as a graph. I’ve written a little app that visualizes such a graph, and here are some screenshots of websites that I often look at.
I’ve used some color to indicate the most used tags in the following way:
blue: for links (the A tag)
red: for tables (TABLE, TR and TD tags)
green: for the DIV tag
violet: for images (the IMG tag)
yellow: for forms (FORM, INPUT, TEXTAREA, SELECT and OPTION tags)
orange: for linebreaks and blockquotes (BR, P, and BLOCKQUOTE tags)
black: the HTML tag, the root node
gray: all other tags
Here I post a couple of screenshots, and I plan to make the app available as an applet, so that anybody can look at their websites in a new way.
Update: Here it is: http://www.aharef.info/static/htmlgraph/
CNN has a complicated but typical tag structure of a portal: Lots of links, lots of images. Similar use of divs and tables for layouting purposes. (1316 tags)
