How can one effectively draw an Edgeworth box to illustrate the concept of Pareto efficiency in economics?

To effectively draw an Edgeworth box to illustrate Pareto efficiency in economics, you should first draw a square representing the total resources available in an economy. Then, draw two overlapping circles within the square to represent the initial allocation of resources between two individuals. Next, show a new allocation of resources that improves one individual's well-being without making the other individual worse off. This new allocation should lie outside the original circles, demonstrating Pareto efficiency where no one can be made better off without making someone else worse off.
