What is a tornado chart?

A tornado chart (also tornado diagram) is a variation of the butterfly chart, in which the bars are organized in descending order—the shape is similar to that of a tornado, hence the name.

A tornado chart is a graphical representation of a sensitivity analysis that demonstrates the correlation between values and a given output. By determining which variables have the largest impact on the outcome, one can assess the risk and make a decision.
