A tag cloud is a visual representation of text data, typically used to depict keyword metadata i.e., frequency, weights, relevance or importance. The differences are made aware using font colors and/or sizes, where a lighter, more brilliant color or a bigger size usually refers to more relevant tags, and vice versa.
Tag clouds are used to display the most prominent concepts or keywords in a site or domain as the visual appeal helps distinguish the relationship among the tags; or as a way to explore a site by linking tags to related content.
