anyone plotting coastlines?

Hello folks,
a beginner....i'm struggling with trying to understand how to plot a
coastline.  i have sets of points forming line segments but can't see how
to use the visad data set types to connect the dots.  i'm sure the examples
are there - but so far i haven't been able to find them.

do i use the IrregularSet class?  what to i do to implement? code snippets
welcome & appreciated.....


Also, i've got a set of Quikscat wind speeds at irregular points in a
scalar and am about to write an objective analysis class to fill in the
holes so i can isocontour.  i see hints of grid interpolation methods but
still find it hard to understand how to implement (i'm not that familiar
with how the pieces fit together) - so find myself resorting to custom code
to keep my spirits up.  suggestions welcome here too!

having fun,
-john
