Word clouds are becoming increasingly popular in data science and analytics. They are successors of tag clouds or better said younger siblings.

Word clouds are used as a tool to extract essence of some text corpus and to represent it in a graphic form. Words with the higher frequency are shown bigger and those with lower frequency smaller or even excluded. This is the basic concept but the algorithm is quite a bit more complex. But is it possible to apply the word cloud algorithm on custom text without coding?
