A load control system may be configured using a graphical user interface software. The graphical user interface software may display a first icon and a second icon. The first icon may represent a first electrical device and the second icon may represent a second electrical device. The first icon and the second icon may represent the relative location of the first electrical device and the second electrical device within a load control environment. The graphical user interface software may display a line from a selected icon (e.g., first icon) to a cursor. The graphical user interface software may adjust the line from the selected icon, for example, as the cursor moves. The graphical user interface software may define and store an association between the first electrical device and a second electrical device, for example, in response to the user selecting the first icon and the second icon.
