Tag clouds

Verrry cool tag clouds.
A 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, both finding a tag by alphabet and by popularity are possible. The tags are usually hyperlinks that lead to a collection of items that are associated with a tag.

In principle, the font size of a tag in a tag cloud is determined by its incidence. For a word cloud of categories like weblogs, the frequency of use for example, corresponds to the number of weblog entries that are assigned to a category. For small frequencies it's sufficient to indicate directly for any number from one to a maximum font size. For larger values, a scaling should be made. In a linear normalization, the weight t_i of a descriptor is mapped to a size scale of 1 through f, where t_min and t_max are specifying the range of available weights.

for t_i > t_min; else s_i = 1

• s_i: display fontsize
• f_max: max. fontsize
• t_i: count
• t_min: min. count
• t_max: max. count
