missing the 3D wavefield example

[ghost]

Hello Cyril,

I want to do an animated 3D xyz plot, on datoviz website homepage the wavelike 3D thing above the scatter plot looks promising, could you add it as an example or provide me with anscient material that I could take myself out of bitrot :)

Thanks, kudo for datoviz, looks terrific.

You'll find some bits here:

https://github.com/datoviz/datoviz/blob/main/src/mesh.c#L308
https://github.com/datoviz/datoviz/blob/main/src/mesh.c#L209

The idea is to generate a regular triangulation of a 2D grid, with the height z of each vertex depending on x, y, and display this as a regular mesh.
