A Butterfly chart is a chart where two entities are compared side by side using scales meeting at the center. Due to its shape, the chart resembles a butterfly and hence the name. These charts are sometimes also known as Funnel or Tornado Charts though I find “butterfly” to be a better description as it allows for a greater variation in shape than a funnel or a tornado does: http://www.databison.com/butterfly-chart-excel-chart-with-dual-converging-scales/.
