This example displays a dense scatter of ellipses that are randomly positioned and colored based on indices from 0 to 20, iterated via double mapping within a React component. The SVG output uses hardcoded width and height attributes, with each ellipse’s radius, fill, and stroke set inline. The code imports React and ReactDOM libraries, and uses `Math.random` for positioning, while rendering is handled by `ReactDOM.render` into a root div. The visual is a simple, colorful grid-like pattern with overlapping shapes, emphasizing React’s capability for dynamic SVG generation.
