Text visualization

So far, we have been dealing only with numeric datasets. There is a vast world of other kinds of information that visualization experts are interested in. A vast amount of text data is present in websites, books, logs, and different documents. They tend to be unstructured and not as nice-behaving as numeric datasets. Text visualization has been gaining momentum in recent days, and there are interesting and insightful techniques being developed in the visualization community. In this section, to demonstrate Mathematica's capability to handle text data, we will build a small tool from scratch to visualize the evolution of frequent words over the length of a text document.

A modified word cloud

We have all seen the word cloud. The word cloud is a simple concept that points out the underlying theme words in a document just by counting the frequency of occurrence for each particular word and rendering the words in a diagram with the font size being proportional to the frequency...
