ListContourPlot for irregular sampling

I need to generate contour plots of data which are not sampled on an evenly
spaced Cartesian grid. ListContourPlot ony accepts data in the form of an
nxm matrix of heights z which are evenly sampled, i.e.

        data = {z11,z12,z13, ...,z1n},
               {z21,z22,z23, ...,z2n},
               ...
               {zm1,zm2,zm3, ...,zmn}};

whereas my data have the following structure

        data = {{x1,y1,z1},{x2,y2,z2}, ..., {xm,ym,zm}};

i.e. each height is also assciated with its own x and y coordinate.
Does anybody know about a package to plot data with this structure?

Thank you in advance!

Stefan
