ALTQ statistics?

[Charlie Schluting]

Does anyone know of any statistics tools that do a good job summarizing 
ALTQ queuing?
Perhaps with an rrd graph of some sort?

I just started using shaping, and its great.. but some time-based view of 
the following data (or more) would be really interesting to see.
