[Feature Request] Add a pgfplot backend (possibly, using the pgfplot crate)

[GuillaumeDIDIER]

What is the feature ?

PGFPlot is the LaTeX package to generate publication quality plots. The feature would be to add the ability to generate PDF and/or LaTeX code for plots as a backend for plotter-rs.

The crate PGFPlot (https://crates.io/crates/pgfplots) presents an basic API that helps generating such plots from rust, which could help build the feature faster.

(Optional) Why this feature is useful and how people would use the feature ?

In most venues in computer science academia, (and maths), papers are usually typeset with LaTeX, and high-quality LaTeX plots fit best in such papers. More generally it enables people writing LaTeX document to generate figures using plotters.

The ability to out-put as PDF (using tectonic) in the pgfplot crate also bring those high-quality plots as PDF for many other uses.

Additional Information

Ecosystem like Julia or matplotlib have similar features to output to LaTeX, (with varying quality of support).
