2D Implicit Plot

In his book UNKNOWN QUANTITY, on page 257, John Derbyshire presents the 4th degree polynomial

4*(x^2+y^2-2*x)^2+((x^2-y^2)(x-1))(2*x-3) = 0

which plots as the beautiful "Ampersand Curve"

When I tried to do this in Maple 11, with a 2D Implicit Plot, the plot was broken, discontinuous, and different when I tried again.

 

Is this beyond Maple's capability, or can someone suggest what I may have done inadvertantly incorrect?
