This React starter demonstrates a minimal data-visualization setup, rendering a static "Hello React!" message centered on the page. The example uses React 16.13.1 and ReactDOM to mount a functional `App` component into a root div, with CSS styling controlling the font size and alignment. It serves as a template for integrating React with visualization libraries, showing the basic structure for building interactive charts or graphs. The rendering approach relies on React’s virtual DOM and the `ReactDOM.render` method, with no external data sources or advanced visualization APIs employed.
