Sorry, I put the wrong picture :(
here, it's the good one.

let z = a + ib
f(z) = c +i d

Represented in POV in this way :
a >> x axis
b >> z axis

arg(c + id) >> the color in HSL space with H = arg and L = logaritmic
function of module between 0 and 1.

module(c + id) >> y axis with a logarithmic scale
