[NBLUG/talk] Graphing implicit equations

[Lincoln Peters]

Is there a Linux program that can graph implicit equations?  The only
programs I'm aware of are for Windows or Mac, and I can't find anything
in the Debian repository capable of working with implicit equations (a
search for a package whose name and/or description contains the word
"implicit" fails to deliver any calculus-related packages).
