The burst damage from Electrocute is both easily accessible and highly beneficial to Graves wanting to blow up enemy champions
Sudden Impact allows you to gain a bit of Lethality after sliding in with [E] for more burst damage.
Zombie Ward is a great rune choice on junglers who often look to invade for deep wards. The extra bit of extended vision allows you to keep track of the enemy jungler for long periods of time.
The high base damage on [Q] and [R] ultimately grant Graves significant healing in duels.
