A Wordle is a "beautiful word cloud". You can put them on tshirts or posters they look so good. Check out the Wordle site for more info.
The plugin only outputs text which can then be used to create the Wordle. It doesn't actually produce the image. The output will therefore not be particularly helpful for ordinary viewers of your site. It is recommended that you make a private page and use the shortcode on it.
Go to http://www.wordle.net/create and paste in the text. You can then customise the output.
Each tag has a unique term ID. You can discover the ID for a term by following these steps:
Log in as admin and go to admin dashboard.
Click on "Tags" in the "Posts" section on the left hand side of the dashboard. You will see a list of tags.
Mouseover the tag you are interested in and take a look in the info bar at the bottom of the screen. You should see the tag_ID as a param for the tag link. This is the Term ID.
