• A word cloud (also called a tag cloud), is basically an infographic that indicates the frequency of words in a collection of text (e.g., tweets, a text document, a set of text documents).

• Here we use the wordcloud2 package and the demoFreq dataset, containing file of words and their frequency, which ships with it.
