How does an input output chart work?

An input-output chart is a tool used in economics to represent the relationships between different sectors of an economy. It displays how the output of one sector serves as an input to another, illustrating the flow of goods and services. Each row typically represents the outputs of an industry, while each column represents the inputs required by that industry. This chart helps to analyze the interdependencies within an economy and can assist in understanding the impact of changes in one sector on others.
