This visualization shows part of the Dr Seuss story Green Eggs and Ham. The visualization technique is a recurrence plot, which represents each word of the text as a square running diagonally down the page. When a word is repeated in the text, a square is drawn where lines from the pair of points would meet. You can see the word a square represents by keeping your mouse still above the square for 1 or 2 seconds. A diagonal row of points shows a repeated sequence of words. The closer to the diagonal points appear, the more recently they were repeated. A recurrence plot shows the overall frequency of repetition, but also shows where in the text repetition occurs.
