No data sets are provided with the -triplot- files on SSC. But some are
wrapped in the .zip file corresponding to my 2008 London users' meeting
talk.
http://repec.org/usug2008/Cox.london082.zip
They include data for the 2000 and 2004 U.S. Presidential elections,
although half the point of using those as examples there is that triples
for (Dem, Rep, other) are crowded in one part of the data space.
The talk also discussed _alternatives_ to triangular plots for such
data, but that is a story to be developed elsewhere, perhaps in a future
Speaking Stata column.
The first example's data are (for the United States)

That example is discussed in
<http://www.stata-journal.com/sjpdf.html?articlenum=gr0004>
around Fig.15. If you look closely at that Figure, you can see the
effects of a small bug, a grid of horizontal lines corresponding to
invisible y axis labels. That bug has now been fixed.

I don't recognize the data set in the help file examples. Is it
available?
