a.k.a. word cloud
A visual display of the word content on a website, specifically of user-generated tags attached to online content, using color and font size to represent the prominence or frequency of the words or tags depicted. Whether it's a data cloud (which displays data such as population or stock market prices instead of words) or a text cloud (the visualization of word frequency in a given text as a weighted list), it's an easy way to see the most popular content on a website.
