Tag cloud

A tag cloud (also known as a word cloud or weighted list in visual design) is a visual representation of text data which is often used to depict keyword metadata on websites, or to visualize free form text. Tags are usually single words, and the importance of each tag is shown with font size or color. When used as website navigation aids, the terms are hyperlinked to items associated with the tag.

Implementations of tag clouds also include text parsing and filtering out unhelpful tags such as common words, numbers, and punctuation. There are also websites creating artificially or randomly weighted tag clouds, for advertising, or for humorous results.
