Agreed, SmokePing is exactly what you want. You will have to change the 
step and pings settings to allow collecting data at the resolution you 
want, but otherwise it gives you what you need by wrapping RRDTool with 
ping data collection (as well as a number of other probes) and a 
visualization tool for graphing.

Note that you could accomplish something similar on your own (see 
http://www.void.gr/kargig/blog/2007/03/21/round-trip-and-packet-loss-stats-with-rrdtool/) 
but with SmokePing already available you might as well use that.
