All works are done with the use of mathematical equations or inequalities:
1. The original graph of the equation fun(x,y) = 0.

2. Add two circles as eyes, a pear-shaped quartic as nose, and a bicorn as mouth.
    [ Pear-shaped Quartic: b²x² + y³(a + y) = c ]

3. Add some boundary curves.

4. The unwanted regions. (They are graphs of inequalities on the coordinate plane.)

5. Color the unwanted regions white.

6. The finished result.
