This example shows a grid of colored squares scattered across an SVG canvas, with each square’s position and color determined by nested JavaScript `map` functions over an array of integers from 0 to 100. The inner `map` iterates over the same array inside the outer `map`, generating a square for each combination of coordinates, with random placement and RGB fill values derived from the loop index. Built with React and ReactDOM, the visualization uses SVG `<rect>` elements, with rendering handled via the production React build.
