PSTricks drawings can't be compiled under pdflatex and lualatex (Frequently done errors #5). Instead, compilation with XeLaTeX is preferred if you need to use .jpg/.png/.pdf images in your project.
But if you absolutely need to compile with pdflatex, this example demonstrates how to use PStricks with pdflatex using
auto-pst-pdf on Overleaf (But you still can't use .jpg/.png/.pdf images within your PSTricks drawings).
Our searchable collection of LaTeX examples is a great place to look when you're using a LaTeX package for the first time (or the first time in a while!).
Show off your awesome LaTeX skills by contributing examples to the gallery. You can publish any Overleaf project with a couple of clicks.
New examples of LaTeX packages and techniques are added all the time. Follow us on twitter for the highlights!
