Stock and Flow Diagrams

Stock and flow diagrams are visual tools used to represent complex systems, showing how different parts interact over time. "Stocks" are accumulations or quantities, like the amount of water in a tank or money in a bank account. "Flows" are the rates at which the stocks increase or decrease, such as inflow and outflow of water or money. These diagrams use arrows to show the direction of flows, helping to understand how systems change dynamically. They are commonly used in fields like economics, ecology, and engineering to model and analyze system behavior.
