3.1.2 Relationship between flow and steps
The user creates each unit of processing in a flow by dragging plug-ins from the Plug-in view to the Flow view. Each plug-in dropped into the Flow view is called a step. A flow is created by placing the steps required to execute a task and connecting them with relational lines. The following figure shows the relationship between a flow and steps.
