WPF Tag Cloud
Capture users’ attention on the most important key words or phrases (“tags”) like rolling thunder by weighting on frequency of occurrence, importance or your own scoring algorithm, and then presenting those with the highest scores bigger than all the rest.
Assign any enumerable collection of data, specifying the properties to use for each tag's Display and Weight.
Weights and Sizes
Customize a tag cloud's range of weights, and these will be mapped linearly to a corresponding scale (and vice versa).
Items appearing in the cloud are fully templatable, allowing you to customize the format of tag content, or scale any content within a tag.
