SVG is nice for its simplicity, but PDF is the gold standard for transit maps. Also there don't appear to be any SVG converter tools that support all the features we use (CSS styling, dominant-baseline attribute).
Some challenges:
PDF/postscript doesn't have circular arcs, just cubic bézier curves
PDF requires embedding fonts in the document (I think; it might be possible to not include them, but that reduces portability)
PDF requires embedding any styling in the document. This requires us to either parse the CSS, or provide some way of encoding styling that is readable by the program.

https://docs.rs/pdf-writer/0.6.0/pdf_writer/ is probably useful.
