gnuplot generally only does explicit or parametric curves, not implicit 
ones like the above.  But you can fake it to some extent by asking for 
z=0 contour of the surface z = f(x,y)=(x^2+y^2-1)^3 - x^2*y^3:

gnuplot> f(x,y) = (x**2+y**2-1)**3 - x**2*y**3
gnuplot> set contour base
gnuplot> set cntrparam lev discrete 0
gnuplot> set isosamp 50
gnuplot> set view map; unset surf
gnuplot> sp [-1.5:1.5][-1.5:1.5] f(x,y) w l
