This example presents a minimal React and D3 starter template, displaying an empty SVG canvas within a React application. The code sets up a 960 by 500 pixel SVG element using React’s JSX syntax, rendered into the DOM via `ReactDOM.render`. It imports D3 v7 and React 17 from CDN links, with all styling handled by CSS that removes page margins. The visualization currently shows no data or chart, serving purely as a foundational scaffold for building interactive D3 visualizations within the React framework.
