A concise React starter template demonstrates a minimal integration of React with D3. The app renders a single `div` element containing the text "Hi react" by mapping over an array generated with `d3.range`. React 17 and ReactDOM handle the component lifecycle, while D3 v6 provides utility functions. The code displays a static result without interaction, using `ReactDOM.render` to mount the component into the root element. It serves as a foundational example for combining React’s declarative UI with D3’s data manipulation capabilities.
