This example demonstrates a minimal React application that renders static SVG shapes, including a large purple circle with a white stroke and a smaller white circle, on a dark gray background. The code uses React 16.7 and ReactDOM 18.3.1 to mount an empty `App` component to the `#root` element. The SVG elements are defined directly in the HTML file, while `bundle.js` contains the JavaScript logic. The visualization relies on SVG markup rather than any data-driven library, focusing on basic layout and styling.
