Causal Loop Diagram is the behavior of a system by showing a collection of connected nodes and the feedback loops created by the connections. It is a cycle in which the effect of a variation in any variable propagates through the loop and returns to the variable reinforcing the initial deviation. It is a foundational tool used in system dynamics, a method of analysis used to develop an understanding of complex systems. A balancing loop is the cycle in which the effect of a variation in any variable propagates through the loop and returns to the variable a deviation opposite to the initial one, if a variable increases in a balancing loop the effect through the cycle will return a decrease to the same variable and vice versa.
