React Charts - Pareto Chart

In this demo, the DevExtreme Chart component is used to create a Pareto chart. This example of a Pareto chart summarizes complaints about the service provided by a pizza shop. From this chart, the pizza shop owner may infer that to satisfy most of the customers, he or she needs to eliminate two most frequently encountered issues: delayed delivery and cold pizza.
