Hello HTML!
This example demonstrates a minimal React application rendering a single yellow circle with a black outline as an SVG graphic. The code imports React and ReactDOM directly from UNPKG-hosted CDN libraries, defines a functional component that returns SVG markup, and mounts it into the page’s root element. It also includes a local ES6 module (`myMessage.js`) exporting a string, though that string is not displayed. The visualization serves as a simple introduction to combining React with SVG for declarative drawing.
