Name of Viz: Butterfly Chart

Authors: G.Adashek & D.Flores


The Butterfly chart, also sometimes known as a tornado bar chart allows to compare 2 data sets side-by-side.
This provides a quick analysis of variances and is a simple comparison chart.
Use the tooltip in this custom viz to easily show the variances.
