The first sets are from polynomials in the form `z³ + z² - z + a` where `a` is a number ranging from -1 to 1.
Then they're from polynomials in the form `a + z - z³/6 + z⁵/120`.
And finally, the last sets, are formed on the function `f(z) = sin(z + b)`, which is an infinite polynomials. `b` is a number ranging from -2π to 2π.

The colors of each set are based on the value `a` or `b` (depending on which the set uses).
