What tools do you use?  What do you like about them, and (other than
their price) where could they be improved?

I'm putting together everything I've got so far in order to come up
with a few key areas we can focus on for the visualization.  I'll send
it out when it's ready (sometime next week most likely) for feedback.
Right now it looks like the big areas are comparing historic traffic
data (or various types) with current traffic in order to more easily
spot changes.
