A field of small, semi-transparent colored circles is scattered randomly inside a large circular boundary, creating a compact cluster effect. The example generates a grid of coordinates using a simple mathematical loop, then filters points that fall within the larger circle’s radius. React renders the SVG elements, including the boundary circle and each small `circle`, with randomized positioning and fill colors based on grid values. The visualization demonstrates a basic collision detection and layout approach using React and SVG, without external data or animation libraries.
