Word clouds for visualization

A word cloud is an image made up of words in which the size of each word indicates its frequency.

It is an effective promotional image for marketing campaigns.

In this exercise, you will create word clouds using the words in a text corpus.

The refined text corpus that you created for "telemedicine" has been pre-loaded as corp_refined.

The libraries wordcloud and RColorBrewer have been pre-loaded for this exercise.
