You can add and connect pipeline components using their respective editors. Alternatively, you can connect them graphically in the Pipeline Diagram editor.
To connect pipeline components graphically:
Choose Pipeline Diagram from the View menu to display the Pipeline Diagram.
Click the component that you want to serve as the data source to highlight it.
Drag the black square in the center of the highlighted component to the component you want to connect it to. A line with an arrow indicating the direction of the data flow appears between the components.
