Interpolating 2D non-uniform Data

Hi, I have data of a 2D function (W(x, y)) in a non-uniform grid. Here you can see how it looks like:

```
data = CSV.read(file_path, DataFrame)
W = data[:,2]
x = data[:,3]
y = data[:,4]
plotscatter(x, y, W)
```

As the data is non-uniform, I can't seem to manage to make it work with the interpolator, but I really need to create an interpolator for this data. Does someone know how to do it?

Best Regards.
