Variety is an important factor in the reader's level of interest. This tab shows graphical distributions of sentence type, length, and word length. Each is a moving average, with word length weighted to the sentences before and after. Remember that rolling waves are good, flatness is boring, and choppiness is jarring. Flow can be altered by adding, removing, lengthening, shortening, combining, or splitting sentences. If you don't see the peaks and valleys in the graphs, try tilting your head to the right.
