This React Starter example renders a grid of overlapping SVG circles, clustered in the upper-left and spread with increasing scatter as the coordinate values grow. It uses React and ReactDOM to build the markup, with nested `map` operations over a numeric array to generate each circle. The fill color is derived from the square of the index, producing a grayscale gradient, while the `cx` and `cy` positions are multiplied by `Math.random()` to introduce random jitter.
