Play around with the "output" setting in perfparse. The hourly
statistics in the presentation is like if you set "daily average" as
output and select a week as timerange in pp for example. The other
distributions are not easily reproducable with pp but a good idea.
Other ideas: logarithmic scales on both axes, fourier analysis to find
frequencies ("is the high cpu load frequently or infrequently") and
eventually one also could try to do correlation calculations ("does this
high cpu load come from a high number of processes or from high network
load?").

Afaik gnuplot is not very good to blend in other programs. You first
would have to generate a command, send the command and data (in a pipe)
to gnuplot and wait for it to generate a file. This file then has to be
sent to the webbrowser.
Ideally a graphing tool would be compiled into the cgi. But that's only
a opinion.
