How to get unique visitor by label

Hello.
I need your help again.
I need see in the dashboard a report with the "unique_visitors" by url or by label ( similar Actions/Pages ) . example :
url unique_visitors
www.mysite.org/forum --> 20
www.mysite.org/video/funny --> 45
www.mysite.org/tips ---> 14

Can you tell me , where i do start ?

thanks.
