This preview illustrates how a `draggedConn` would connect to a `staticConn`, effectively replacing a `replacedBlock` that is currently connected to the `staticConn`. The method takes three parameters: `draggedConn` (the connection being dragged), `staticConn` (the stationary connection), and `replacedBlock` (the block being replaced). The method returns void.\n"]]
