Interactive Prime Sieve Pattern Visualization

This example demonstrates an interactive “prime number sieve” visualization, showing how the distribution of numbers evolves into recognizable 2D patterns as the sieve process progresses. The key mathematical ideas are prime numbers and the sieve mechanism (iterative elimination), together with mapping selected values to coordinate-based points/labels to reveal structure in the plane. In the GeoGebra construction, undefined elements are handled with RemoveUndefined, while Textfield supports interactive text input/output. The objects include cols and a structured set of labeled coordinate groups A1..F1, A2..F2, …, A7..F7, which organize and display the sieve results in a grid-like arrangement. Suitable for secondary to early university learners, and effective for classroom demonstrations and exploratory learning of number-theoretic patterns through graphing.
