Intro to using TikZ and PGFPlots to create high-quality figures
TikZ and PGFPlots are TeX packages that enable high-quality figure generation using the same environment as your LaTeX document. They are typically more effort than other plotting packages, so not an approach we use every time, but when you want a very seamless look this can be the way to go (note that we generated all the figures in our optimization book with TikZ/PGFPlots, one of which is the cover image for this video: https://mdobook.github.io). This tutorial is by Cibin Joseph, a postdoc in our lab.
