no conformal maps

[jverzani]

This example from the tutorial no longer works due to changes in Plots. Perhaps there is a workaround:

f(x,y) = x
plot(f ≧ 1/2, map=z -> 1/z)

Carry out this example I've got the drawing which is displayed in the example docs (Maps). So it seems to work. I'm using Julia 1.5 and ImplicitEquations v1.0.1, Plots v1.7.3 and PyPlot v2.9.0.
However link several [http://mathfaculty.fullerton.edu/mathews/c2003/ConformalMapDictionary.1.html] does not open the web page.
