This example shows a minimal React application that renders a simple greeting message alongside a static SVG smiley face. The SVG contains three circles—two smaller ones for eyes and a larger yellow circle with a black stroke for the head—drawn with fixed coordinates. The code uses React’s `createRoot` and `StrictMode` from `react-dom` to mount the `App` component. The SVG is embedded directly in the HTML body, bypassing React, while the `App` component outputs only the text headings via JSX.
