Data visualization course - Fork of Let's Make a Face Part I
A React-based smiley face is partially constructed using layered SVG circles. The example shows a yellow circular head with black stroke and two dark eye circles, leaving the face incomplete. The code imports React and ReactDOM from unpkg, renders a static SVG directly in the HTML, and uses JSX to display a “Hello JSX” heading via `ReactDOM.render`. The visualization runs in a browser with SVG rendering.
