Feedjit's live traffic feed shows statistics on your website in real-time. It shows:

• Which city and country your visitors are in
• Which website they arrived from, if any
• Which page they visited on your website
• Which external link they clicked to leave your site, if any

Feedjit widgets are updated in real-time. Your traffic feed is updated as each visitor arrives on your site. The update occurs before the widget loads which means that each of your visitors can see their own location displayed.

Feedjitprovides a realtime map (or list) of the geographic location of visitors to your site, information about popular pages, and a "related content" block. And now you can use Feedjit on your drupal site.

And now Feedjit module are available for Drupal 6, it still on development version but you can try it. I already use Feedjit module in one of my sites. 

NOTE: Feedjit does not support running in a subdirectory. I.e. http://yoursite.com/ is fine, but not http://yoursite.com/drupal/. See the Feedjit Traffic Feed FAQ.
