implicits equations

I tried and didn't find the way of plotting implicit equations such as
x^2+y^2=1
in that case I can use the function circle  but most of times things are
not so easy  If I want to plot the general equation of a conical  eg :
ax^2+by^2+cx+dy+exy+g=0 
without knowing if it's an ellipsis or a hyperbola i can't use the
function circle !

So is there anyway to deal with such a problem ??
 
Thanks to all
