This example shows a minimal React application that combines a “Hello” heading with a Map component. The map logic is currently disabled, with a placeholder function component returning a simple greeting instead. The code imports `React`, `ReactDOM`, and `react-map-gl`, though the map library is not actively used in the rendered output. The project includes an `index.html` referencing Mapbox GL CSS and React production builds, with the app mounting to a root element via `ReactDOM.render`.
