{"version":"1.0","type":"rich","title":"React Starter","description":"A React starter example renders an empty div by default. It imports React, ReactDOM, and the full D3 library. The component uses a `useRed()` hook (likely a typo for `useRef()`) to reference the DOM node for chart placement. The data file defines a hierarchical JSON structure of world continents and countries, but the code does not currently visualize it. This demonstrates a minimal setup for integrating D3 within a React component lifecycle.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
