This example shows a simple smiley face drawn with two eyes and a yellow circular head on a blank SVG canvas, with no interactive or animated behavior. The page combines React and D3 v6 by loading both libraries via CDN in the HTML, while the SVG shapes are defined directly in the markup using circle elements with fixed coordinates and stroke styling. A separate React component renders a static "Hello JSX" heading into a root div, demonstrating a minimal integration of React’s component syntax alongside raw SVG rendering.
