I would like to post a number of charts on our intranet site and nightly swap
out the .csv data files driving the charts. I would like to run several cron
jobs to query number sources and simply overwrite the various .cvs files so
the data is updated nightly and the graphs/charts are dynamically updated.

The default browser is Netscape on Linux boxes. So "Add interactivity" does
not seem to be a valid option. We have NO plans to update the data from the
browser, simply recreate the .csv file nightly to repost.

We are running Excel 2002 SP3,
