This "squared spiral" was formed by modulating the log spiral with a sine wave. The resulting figures uses more of the display area than the raw log spiral. The plot also shows the words sorted by word length, which results in a nice balance among the subtree graphs. Large subtrees tend to begin with shorter words, like "A", "I", "YOU", and "WHAT". Longer words tend to have fewer branches. Arranging the graph in this way, the branches near the center of the spiral are generally fewer than the branches near the outside. The picture makes it easier to see the subtrees than, say, an alphabetical ordering, which agglomerates many subtrees at the center.
