A bar chart showing frequencies in descending order of occurrence is called a Pareto chart. It is used to identify the most significant factors causing a problem, and it helps to prioritize areas for improvement. The Pareto chart is named after Vilfredo Pareto, an Italian economist who observed that 80% of Italy's wealth belonged to 20% of the population.
