Women visiting the graveyard

Q: I need to know. Can a woman go to the graveyard for ziyaarat? Did Hazrat Aaisha (Radiyallahu Anha) go to the graveyard for ziyarat of her brother. First Rasulullah (Sallallahu Alayhi Wasallam) said don't go and the he said you can go to Aaisha (Radiyallahu Anha). Can you please explain me about women and children going to the graveyard.
