                Sentence length can be a powerful tool in your writing and you should
                use it purposefully. Longer sentences can lure a reader in, while shorter,
                more stacatto sentences keep that attention with fast-paced action.
              </p>
              <p>
                This chart shows the length, in words, of each sentence through your
                document. Groups of shorter sentences likely read faster, while groups
                of longer sentences may be dense or hard to read.

                Selecting an area on the chart will zoom in to focus on just that area.
                Double-clicking the chart will reset the zoom back to your entire document.

                  <span class="red lighten-4">Here are five more words.</span>
                  <span class="red lighten-4">Five-word sentences are fine.</span>
                  <span class="red lighten-4">But several together become monotonous.</span>
                  <span class="red lighten-4">Listen to what is happening.</span>
                  <span class="red lighten-4">The writing is getting boring.</span>
                  <span class="red lighten-4">The sound of it drones.</span>
                  <span class="red lighten-4">It’s like a stuck record.</span>

                  <span class="green lighten-4">It has a pleasant rhythm, a lilt, a harmony.</span>
                  <span class="blue lighten-4">I use short sentences.</span>
                  <span class="green lighten-4">And I use sentences of medium length.</span>
  
                  <span class="purple lighten-4">And sometimes, when I am certain the reader is rested, I will engage him with a sentence of considerable length, 
                  a sentence that burns with energy and builds with all the impetus of a crescendo, 
                  the roll of the drums, the crash of the cymbals–sounds that say listen to this, it is important.</span>

                <p>
                  <span class="green lighten-4">So write with a combination of short, medium, and long sentences.</span>
                  <span class="green lighten-4">Create a sound that pleases the reader's ear.</span>
                  <span class="blue lighten-4">Don't just write words.</span>
                  <span class="yellow lighten-4">Write music.</span>
