Word cloud or tag cloud (or weighted
list in visual design) is a visual depiction of user-generated tags,
or simply the word content of a site, used typically to describe the
content of web sites. Tags are usually single words and are
typically listed alphabetically, and the importance of a tag is
shown with font size or color. Thus both finding a tag by alphabet
and by popularity is possible. The tags are usually hyperlinks that
lead to a collection of items that are associated with a tag.
