Word Tree

Word Tree is a visualization of a set of words, i.e. text data, in a hierarchical way.

Invented by the duo Martin Wattenberg and Fernanda Viégas in 2007, the Word Tree chart type can be helpful in displaying which words most often follow or precede a target word or phrase (e.g. "AnyChart is...") and in showing a hierarchy of terms.

Words in a Word Tree chart are shown as branches going from the root word. The font size of each word represents its weight determined by the frequency of occurence / number of children.
