World Vistor Map on my site

I have searched for a script but cant find one that will display the map itself on my page. I want it to show user locations of the people that are currently on my site and refresh overy 60 seconds.

Does anyone know of something like this? If not, what would something like this cost custom?

Thanks in advance.

I am looking for something that will not send my users to another site.
