A word cloud (or tag cloud, or weighted list in visual design) is a visual representation of text data. Tags are usually single words, and the importance of each tag is shown with font size or color.
This format is useful for quickly perceiving the most prominent terms and for locating a term alphabetically to determine its relative prominence (def: wikipedia). In R, two libraries allow
to create wordclouds: Wordcloud and Wordcloud2. You can find examples of wordcloud utilization below.
