React Web App Prototype

I’m building a small React-based web application and need a developer to create a minimal working prototype. The core tasks are:

• Integrate a simple data-visualization component that can render live charts. I’m flexible on the library—Chart.js, D3.js, Highcharts, or another well-supported option that fits quickly.
• Wire up real-time updates so the chart refreshes automatically when new JSON data arrives from a placeholder endpoint or mocked websocket.

Keep the setup lightweight: a clean React project, concise file structure, and clear README so I can extend it later. No need for full user authentication or polished UI; I just need the foundational code that proves the live-data flow works.

Please comment your code, note any npm dependencies, and provide brief instructions to run the app locally.
