Warning

Wordclouds are useful for quickly perceiving the most prominent terms. they are widely used in media and well understood by the public. However, they are criticized for 2 main reasons:

Area is a poor metaphor of a numeric value, it is hardly perceive by the human eye
Longer words appear bigger by construction

To put it in a nutshell, wordclouds must be avoided. You can read more about that in data-to-viz. Why not considering a lollipop plot or a barplot instead?
