The AI says:

The SVG representation effectively creates a visual of a key, a small metal instrument used for securing and gaining access to something, typically a lock. The 'Shaft' of the key is the long, slender part that's inserted into the lock, represented here by a purple rectangle. The 'Head' of the key, illustrated by a purple circle, is the part where the key is held and turned to open or close the lock. The 'Teeth' are the distinctive cutouts on the key, depicted here by white rectangles, that align with the corresponding pins inside the lock. Together, these three components form a recognizable visual of a key.
