Hi,

I don't know if what I describe below is along the lines you ask for,
but here comes two wishes:

1) Full support for drawing implicit curve plots. For some curves,
like a lemniscate
(https://en.wikipedia.org/wiki/Lemniscate_of_Bernoulli) one can easily
succeed by using a parametrisation, but sometimes one end up with
equations and to find a parametrisation might be difficult (not to say
impossible).
sure, see  eg
https://math.stackexchange.com/questions/904782/is-there-a-general-way-to-parameterize-all-implicit-functions
