Thanks! For the graphics I used TikZ, which is a LaTeX package. The TikZ code of all the figures I used in my Ph.D. thesis are available on Github: https://gith

Thanks! For the graphics I used TikZ, which is a LaTeX package. The TikZ code of all the figures I used in my Ph.D. thesis are available on Github: https://github.com/jeroenjanssens/phd-thesis/tree/master/figures/tikz https://github.com/jeroenjanssens/phd-thesis/tree/master/fig... which can be compiled using tikz2pdf: https://github.com/jeroenjanssens/tikz2pdf https://github.com/jeroenjanssens/tikz2pdf You can see a whole lot of other examples on http://www.texample.net/tikz/examples/all/ http://www.texample.net/tikz/examples/all/ TikZ allows for high quality graphics, but if you're not into LaTeX, then the learning curve can be quite steep!
