Tag Clouds are a visual representation for text data, typically used to depict keyword metadata (tags) on websites, or to visualize free form text. Tags are usually single words, and the importance of each tag is shown with font size and/or color. This format is useful for quickly perceiving the most prominent terms and for locating a term alphabetically to determine its relative prominence.
