{"version":"1.0","type":"rich","title":"interaction with react","description":"A React component renders an SVG circle that tracks the mouse position across the full viewport. The circle’s center coordinates update via React state, with the `onMouseMove` event handler feeding client coordinates into a `useState` hook. D3 v5 provides the `arc` import, though the visible geometry relies on plain SVG circle elements. The example demonstrates bidirectional integration of D3’s ecosystem with React’s declarative state management, using the `useCallback` hook to optimize event handling. No data source is involved; the visualization is purely interactive, responding to user input in real time.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
