Currently the 2D plot for unstructured data is done through triangulation and interpolation provided by Matplotlib: https://matplotlib.org/stable/api/tri_api.html#matplotlib.tri.TriInterpolator. I want to find a substitution of triangulation and interpolation in Julia.

There are several options in Julia, but I haven't found a good solution yet. I've looked at

ScatteredInterpolations.jl
BasicIntepolators.jl

These two are pretty similar, but neither of them support linear scatter interpolations, and they both suffer from the OOM issue.

Triangulate.jl is a wrapper over another famous triangle mesh generator. I don't know if it supports linear scatter interpolations.
GridInterpolation.jl is another option, but the so-called simplex grid implementation suffers from performance issues.
NaturalNeighbours.jl is a working package.
