A word cloud is a method of text visualisation for displaying the frequency of words in a given body of text. The frequency of each word is proportional to its size.
Details
Word clouds (also known as text clouds or tag clouds) is a graphical cluster of words depicted in different sizes. The more frequently a word appears in the source, the bigger and bolder the word appears in the graphic. Common words and themes can easily be derived. Words shorter than three characters will not be included.
Output
The example shows a word cloud.
