Sinister plots

I have been monitoring a message system for a while. I have 1000 data samples, each sample has a timestamp and a message count at that point in time. The count is ever-increasing. Can you recommend a tool to produce an interesting, pretty graph that shows activity over time? I'm familiar with gnuplot but don't like the output or the user interface much.

I don't have either one of those. Are they easy? And pretty?
oh, there's also octave, the GNU copy of matlab. also does plots.
Is that easy to use and pretty?
sorry, I have no clue how Octave handles. I guess the graphs are scientifically accurate and clean, but they might not win beauty contests ;)
