Only numbers that are prime will be seen, highlighted in white. All other numbers will be masked in black. The center of the spiral will be in blue. A pattern of diagonal lines will develop, especially when the number 41 is chosen as the center. This program can graphically plot prime numbers with a center number ranging from 1 to 1,000,000.
