I have a time-series dataset that looks like this (a few thousands of entries spanning for a couple of years):
timestamp <TAB> items_added <TAB> items_removed
1286016527 10 70
I want to play with this data, draw it on a plot and do some ad-hoc analysis.
For this particular task I do not want to use gnuplot, rrdtool or R. These tools take some fiddling to get a good plot, and right now I need something more lazy and casual (it is a weekend after all).
Perhaps there is some nice web-service to do this?
Or more casual standalone tool that works on Ubuntu?
