I have a set of data (z) which is dependant on two variables (x and y).

x and y are not linearly spaced, for instance the values for x are 
and the values of y are
2.8265,  6.0901,  8.4037,  9.7438, 15.4105, 16.2210, 18.0747, 27.0028,
32.9710, 33.4117, 36.8778, 47.0123, 47.1012,  64.0642,  64.8562,
66.9691, 70.2852, 85.6802,  89.2302, 93.1160

I've currently got the data in the form of a list of triples i.e. {
{x1,y1,z1},{x2,y2,z2} .....}

I'm trying to fit a model to this data, and as part of that I'd like to
plot it.
 What's the best way of plotting this type of 3D data in Mathematica
(note: I'm a bit of a Mathematica novice).

By the way, the spacing of the independant variables is a feature of the
experiment the data comes from and not a lot can be done about it. 
Also, I'd love to post the actual data  (as it's not proving
particularly easy to fit a model to it) but I pretty sure that my boss
would regard the data as commercially sensitive and forbid me to do so.
