React Starter
This example demonstrates a minimal React application that renders the text “Hello React!” inside a large, centered message div. It uses React 16.10 and ReactDOM to mount the component onto a root div, while the page also loads d3.v5 but does not invoke any D3 functions. The styling is defined in an inline CSS block within an HTML template. The code imports a local SVG file, although the import is unused in the rendered output, and does not visualize or manipulate any data.
