            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.

            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.
