V line: Refers to the shape of a person's jaw. A narrow jaw line that forms a "V" is considered to be a "V Line." In some cases, this aesthetic is achieved through plastic surgery in a procedure known as jaw shaving.
Visual: Refers to the best-looking member of a K-pop group. Each member is assigned a position and yes, the visual is an actual position within a group. The visual is the face of the group. You may find another member to be "best looking," but technically by industry standards he or she is no match for the assigned "visual."
