Actually, there are some nice tools (e.g. GoAccess) that produce pretty graphs. The vast majority of people just want pretty graphs; the more fancy data Google Analytics produces is nowhere near as accurate as the number of trailing non-zero digits would have you believe.

Depending on your userbase, the regular traffic data can be off by significant proportions. I've seen pages where the number of logged-in interactions are higher than the number of Google Analytics hits.
