It might not be the worst to have several implementations. Which of these would be most likely to plot things like cusps and nodes correctly? In my experience, different systems have vastly different ways of dealing with those; sometimes nodes look like Reidemeister moves have been applied to them, so to speak. > But it sounds like if you/they already have code, so it probably would > be easiest to just convert it into the library function. > > It would definitely be great to improve this function.
