What type of graph is a tornado graph best described as?

A tornado graph is best described as a sensitivity graph used to display the relative strength of variables in a simulation model. This type of graph is characterized by its distinctive appearance, where variables are represented on a horizontal axis, with the length of the bars indicating the degree of impact that each variable has on a specific outcome.

In the context of sensitivity analysis, tornado graphs allow analysts to visualize which factors contribute most significantly to the variation in results. Each bar in the tornado graph represents an individual variable or input, with the length of the bar showing how much that variable can influence the final outcome. This helps in identifying key drivers and understanding the range of effects that different inputs can have when analyzed through a model.

By clearly presenting the data in this format, stakeholders can easily assess which variables require attention and potentially guide decision-making processes based on their relative importance highlighted in the graph.
