Circle Packing Diagram - Geometric Arrangement Visualization #1750930 (License: Personal Use)

This diagram illustrates a classic circle packing configuration where four identical large blue circles are placed at the corners of a square, leaving space for a smaller fifth circle centered in the middle. The green background highlights the container boundary, and the vertical scale bar on the right indicates the normalized radius R = 0.21 for the central circle. Two interactive buttons below allow toggling animation to demonstrate dynamic rearrangement or static display.

Used in mathematics education, geometry tutorials, or computational design resources to explain dense packing, symmetry, and optimization problems; matches user intent for visual learning or reference in academic or developer contexts.
