Well, first of all you would have to create an RRD that held one years 
worth of five minute data points, which would be 105120 data points.  To 
graph it via a web page you would have to write your own CGI code to 
interface with RRD, rrdtool can graph historical periods with the 
--start and --end options.

I developed a proof-of-concept to just this using the development 
release, which supports human readable time-stamps, so it was fairly easy.
