This visualization plots Gaussian primes as filled squares on the complex plane, with the pattern emerging across a grid of integers. It uses d3.v5 to render the SVG elements, with a custom `isGaussianPrime` function that checks the criteria for primes on the axes and in the interior. The code generates points by iterating over a symmetric range and applies a static rendering, with a circular clipping mask defining the visible area. The implementation follows Jason Davies’ original approach, though the developer notes that a cached prime-checking function underperforms the simpler dynamic version.
