The numbers at the bottom are the days of the Month (eg, March 1, March 2, etc.).

Hits represent the total number of requests made to the server

Sites is the number of unique IP addresses/hostnames that made requests to the server.
Visits occur when some remote site makes a request for a page on your server for the first time. As long as the same site keeps making requests within a given timeout period, they will all be considered part of the same Visit.
Pages are those URLs that would be considered the actual page being requested, and not all of the individual items that make it up (such as graphics and audio clips).
