A Asp Tag Cloud or word cloud (or weighted list in visual design) is a visual depiction of user-generated tags, or simply the word content of a site, typically used to describe the content of web sites. Tags are usually single words and are normally listed alphabetically, and the importance of a tag is shown with font size or color.
Thus, it is possible to find a tag alphabetically. The tags are usually hyperlinks that lead to a collection of items that are associated with a tag. Sometimes, further visual properties are manipulated, such as the font color, intensity, or weight.
