The custom word cloud plugin will generate word cloud images based on page 
content or the contents of a form POST input named “content”. The cloud is 
specified using shortcode tags on the page where the content or form exist.
<h4>Example 1</h4>
As an example the following entered into a WordPress page will result in a 
page with a word cloud image displayed above the paragraph that is a link 
map with google searches for each word in the cloud:
<pre><code>[cwcloud] 
[cwcimage] 
[cwcmap]

We the People of the United States, in Order to form a more perfect Union,
establish Justice, insure domestic Tranquility, provide for the common
defence, promote the general Welfare, and secure the Blessings of Liberty to
ourselves and our Posterity, do ordain and establish this Constitution for the
United States of America.

[/cwcloud]
</code></pre>
<h4>Example 2</h4>
Another example where a user may enter their own paragraph of text and 
generate a custom word cloud:
<pre><code>[cwcloud post="true" id="mycloud"] 
[cwcmap] 
[cwcimage] 
<form method="post"> 
<textarea cols="40" rows="10" name="content">[cwcpostcontent]</textarea> 
[cwcform] 
<input type="submit" value="Build Cloud" />
</form>
[/cwcloud] 
</code></pre>
<h4>Example 3</h4>
An example of a form with attributes set to some custom default settings and 
the id attribute is not set so a fresh id will be generated for each user 
created word cloud:
<pre><code>[cwcloud post="true" palette="#046, #fe0, #2f2, #82f" width="500" height="250"
word_limit="30"]
[cwcimage]
[cwcdownloadlink]
<form method="post"><textarea cols="40" rows="10"
name="content">[cwcpostcontent]</textarea>
<input type="submit" value="Build Cloud" /> [cwcform]
</form>
[/cwcloud]
</code></pre>
<h4>Attributes</h4>
The [cwcloud] tag accepts multiple attributes and there are some custom 
shortcode tags that can be used inside the enclosed [cwcloud][/cwcloud] tags:
attributes: 
id – specify an id to use for this word cloud image 
i.e. “mycloud”
