with the bundled FVWM release or TWM. You can use DieHard:<p><a href="https://github.com/emeryberger/DieHard">https://github.com/emeryberger/DieHard</a><p>Usage: env LD_PRELOAD=/path/to/DieHard/src/libdiehard.so /path/to/your/binary<p>example: env LD_PRELOAD=$HOME/src/DieHard/src/libdiehard.so $HOME/src/CBofN/bin/mandel<p>Xaos it's a fun software from the 90's, I think today uses QT5 instead of Xaw, but it's virtually the same interface.<p>Another examples would be the ones from the AI Alife Howto's from the 90's.<p>And, finally, there's the uber known Gnuplot, albeit it's from late 80's, but it was widely developed and used in the 90's, and still really powerful to plot from whatever software, as it can use plain text files and you can compile it without QT and WX, making it extremely light on legacy software.<p>BTW, there was some language to create math figures/art declaratively. A la povray, but without raytracing. I can't remember it's name.
It wasn't pic, or PostScript.
