<p>Note that this is a visualization of a <strong>Markov chain</strong>, a common model in text processing. In a Markov chain, each choice of word depends only on the previous word. In this case, a random generator following this model might spit out &quot;dear&quot;, then &quot;sir&quot;, then &quot;william/walter/thomas/thomas's&quot;, by following each word to the most common words that follow it. To make the visualization interpretable, we chose to show only the most common word to word connections, but one could imagine an enormous graph representing all connections that occur in the text.</p>
