You can also embed the following code into your own web page, such as your blog, to get the page's word cloud:
(Note: when you copy the following code to your page, it is your responsibility to make sure that each statement must be in one line. We have seen that when copy and paste to a blog, the server add <br /> at the end of each line. you should manually remove the <br /> such that when you view the source code, it should be exactly the same as the code here).
<script>
function getDynamic(iname){
url = location.href
x = 'http://taporware.mcmaster.ca/~taporware/cgi-bin/prototype/bwordcloud.cgi?source=url&htmlurl=' + url
window.frames[iname].location = x
return true
}
</script>
<div style="width: 300px; height: 280px; float: right">
<iframe name="wordcloud" width="100%" frameborder="0" height="100%" marginheight="0" marginwidth="0" style="border: none">
</iframe>

You can change the values in the line:
