This example shows a minimal React application that renders static text, “React Starter Code,” centered on a goldenrod circle with a black stroke. It serves as a bare-bones template for building data visualizations in React, using the `react` and `react-dom` libraries. The code defines a `BackgroundCircle` component that draws the circle with SVG, while the main `App` component renders simple text via `ReactDOM.render()`. The page loads React from CDN and includes a separate `bundle.js` for the application logic.
