If you have the two functions <code>randPoints</code> and <code>monteDonut</code> in a file and load it into GHCI you should be able to run <blockquote> :m + Graphics.Gnuplot.Simple </blockquote> and <blockquote> plotDots [Aspect(Ratio 1), XTicks Nothing, YTicks Nothing] (take 10000 monteDonut) </blockquote> and the image should be displayed in gnuuplot. Perhaps you don't have <a href="http://www.gnuplot.info/download.html" rel="nofollow">gnuplot installed?</a> (the haskell library is just a wrapper). @rfh: Sorry, I should have made the post into a working haskell module.
