I did recently also a tool for prime numbers visualization: https://ilmenit.github.io/prime-fold/ It's not only for visualization but also discovering of mathematical functions that generate or embed prime numbers using evolutionary algorithms and fitness functions. It has two modes: PrimeFold Mode (2D Embedding): Enter or evolve two functions, f_x(n) and f_y(n), to map numbers to 2D points. Primes and composites are visualized differently. This mode helps you discover spatial patterns and structures unique to primes. Example: f_x(n) = n, f_y(n) = n^2 or simply n, n^2. PrimeGen Mode (1D Generation): Enter or evolve a single function, f(n), to generate numbers. The app visualizes which outputs are prime and how many unique primes are produced. Example: f(n) = 2*n + 1.
