What is a Word cloud?
Word cloud is a visualization tool based on frequency. In its simplest form, only one dimension of information is shown: the font size is proportional to the word frequency, which means that the larger a word is in the cloud, the more frequent the word is in the document.
The word cloud feature takes as input a vector of terms (term labels) and a term frequency matrix (one column per document). A word cloud is displayed per document in the output.
