This is a Flow Node, in which the flow is divided into two branches, represented by two output flow ports. The `Condition` parameter describes the validity of the condition necessary for the loop to function. While this condition is `True`, `Body` will be executed. Inside the body resides all the logic of the loop, described as a collection of joined Nodes. Once the condition is `False`, the main branch (upper right port) is resumed, and the loop finishes its computation.
