This example displays a single, static yellow circle with a black stroke, representing the initial stage of a smiley face. The visualization is built using the React framework and SVG rendering. The code imports React and ReactDom, then defines an `App` component that returns an SVG with a `<circle>` element. The circle's position, radius, and colors are explicitly set in the code, and the SVG is rendered into a root element via `ReactDOM.render`. The data is procedurally generated, not sourced from an external dataset.
