[Feature Request] Surface fitting for simple data, and example that shows the surface in plotly

I want to produce a surface from a combination of data currently in 3 axis, I am using matlab to produce a thin plate spline model and also poly44 and wondered if there are any options to do this with this lib?

**Describe the solution you'd like**
I would like a sample that generates a surface fit for data in 3 axis and produces a Plotly ploy showing the surface and the original data scattered on top.

**Describe alternatives you've considered**
Matlab/Python examples are easy to google but I can include one if needed.
