Flying VFR does not require you to actually navigate by means of visual reference, it just requires you to remain VMC in accordance with the airspace class you are in.
The AIM specifies how flight plans should be filled out, block 8 contains the route of flight:
Block 8. Define the route of flight by using NAVAID identifier codes and airways
