Help with list contour plot

    I have a set of discrete data output from a finite element program. 
The data is in the form
{x,y,z}.  The underlying x-y is not regular, but has bounds, i.e.
0<=x<=a, and 0<=y<=b.  I would like to visualize z using either a
surface or contour plot.  How can I do that?

Thanks a lot in advance.
