This example renders concentric circles with a linear gradient background, creating a visual field of overlapping, transparent rings. The React component `Circles` outputs SVG `<circle>` elements, positioned using trigonometric calculations with random multipliers in the `index.js` file. The circles use the `radialGradient` definition to fill with a Saturn-like color scheme, while a drop shadow filter adds depth. The rendering is driven by React’s `ReactDOM.render` into an SVG element, with the background set via CSS linear gradient.
