This example shows a dense scatter of circles rendered with React and SVG, filling a 960-by-500 canvas with randomly positioned points. The color of each circle derives from a nested loop of `A.map` over a small array, producing a repetitive pattern of red and dark hues. It uses React 16.10 and ReactDOM to render the SVG elements, with circle positions and fills computed inline using the `Math.random` function and arithmetic on the loop index. The code demonstrates a basic React component structure, but the visual output is largely stochastic rather than data-driven.
