Distribution of Primes 2: Prime Point Grid Visualization

① This example visualizes how prime numbers are distributed among positive integers by mapping them onto a square grid, highlighting prime positions to reveal patterns. ② Core mathematical concepts include prime numbers, distribution properties (e.g., intuitive sense of the prime number theorem), sequences, sets, and coordinate mapping. ③ Construction details: Uses GeoGebra commands Sequence (to generate number sequences) and Max (to control grid bounds); objects include m, n (grid dimensions), list1 (prime list), win (window), list2 and list3 (coordinate or marker lists), text1 (text labels), a and b (auxiliary parameters). The mapping assigns each integer to a grid cell and marks primes distinctly. ④ Suitable for high school and above, useful for number theory introduction, observing prime density, and as a math-computing experiment.
