Yes, you can populate a temporary rrd and use it to generate graphs, 
though I honestly have no idea how the performance would compare to 
other approaches.

The magic that you need: As you store each data sample in the rrd, 
specify the explicit timestamp, rather than "N:".

Presumably you've considered storing your entire database in an rrd?
