In this mode, every component is displayed with four connection points.
Dragging one connection point to a target component helps you connect these two components together. A connector will also be generated automatically.
Please note: Connectors are smart lines that you can use to connect any two components in your flow charts. Once a connector is created, selecting the connector shows four line control points. You can then drag these control points to readjust the connector.
