Example: gnuplot + tikz
This is an example for re-creating gnuplot charts with tikz on LaTeX, made possible by adding gnuplot-lua-tikz.sty and gnuplot-lua-tikz-common.tex to your project. (These files can be generated by invoking lua gnuplot-tikz.lua style where gnuplot-tikz.lua can be found in $GNUPLOT/lua/gnuplot-tikz.lua.
(This will work with all engines, not just LuaLaTeX!)

Asymptote 3D graphics
This example shows how to get asymptote 3D drawings working on Overleaf. All the drawings in this example were taken from the Asymptote documentation.
The important bit is to add settings.render=0, to get around the problem of rendering on headless displays (i.e. the compile servers doesn't have a graphics card/display!)
If you download the PDF and open it in Adobe Reader, you'll get interactive views of the 3D objects!

Automatically numbering compounds in chemical schemes
This example demonstrates how the chemnum package can be used to automatically number compounds in reaction schemes created with ChemDraw (saved as .eps files). While the chemstyle/chemscheme package can also be used, its author recommends the use of chemnum as it's deemed to be clearer.
Ideally, the ChemDraw-generated .eps files should contain "TMP1", "TMP2" etc as temporary markers, which will then be replaced with automatically incrementing compound counters using the \replacecmpd command. Switch the LaTeX engine to LaTeX+dvipdf from the project's Settings icon (the gear icon) so that the replacement actually takes place.

Getting psfrag to work in pdflatex
An example using the pstool package to get \psfrag commands working with .eps images in pdflatex. There's a caveat; after the initial compile, if you add more \psfrag or change the replacements, it doesn't auto-update the replacements in the PDF output on Overleaf unless you do a recompile from scratch, or the .eps file itself is updated.
