I wonder if tikz/LaTeX is the best output format for this. When I'm making figures it has been fastest for me to have code that generates 90% the right thing, then tweak as necessary in Illustrator/Inkscape to get different parts to line up, combine subfigures, etc.

If I did anything with neural nets, I might take the time to bolt on an option for output to SVG. EPS or some other vector format would be great as well, but I am not that much of a wizard.
