Exercise 3.1: If the function f returns a non-finite float64 value, the SVG file will contain invalid <polygon> elements (although many SVG renderers handle this gracefully).

Exercise 3.2: Experiment with visualizations of other functions from the math package.

Exercise 3.3: Color each polygon based on its height, so that the peaks are colored red (#ff0000) and the valleys blue (#0000ff).

Exercise 3.5: Implement a full-color Mandelbrot set using the function image.
