Subject: Off topic - scatter plots

Hi all,

I hope you'll forgive the offtopic posting, but my Googling is letting
me down.

Some years ago I came across some nice little data sets that illustrated
how variables could have identical descriptive statistics and identical
linear relationships, yet when plotted in a scatter graph had obviously
different true relationships (one was linear, one was probably quadratic
etc).

Can anyone point me to a reference for the data? I've tried creating
some myself, and it's difficult to come up with anything as neat as this
example was.

Thanks,

Stephen
