Hello HTML
A minimal React and SVG example displays the text “hello” and a centered circle on a 500×500 canvas. The page loads React 16.9 and ReactDOM 17.0.2 from a CDN, while the bundled `index.js` (importing `React` and `ReactDOM`) renders the static SVG markup defined in the HTML. The visualization demonstrates a bare-bones integration of React with inline SVG, using no external data or interaction.
