+### Diverging Bar (or Butterfly) Chart with Neutral Column
+
+Diverging bar charts offer two imperfect options for responses that are neither positive nor negative:  omit them, leaving them implicit when the categories add to 100%, as we did above or put them in a separate column, as we do in this example.  Jonathan Schwabish discusses this on page 92-97 of  _Better Data Visualizations_.
