{"version":"1.0","type":"rich","title":"mouse follower","description":"A mouse follower demonstrates a simple interactive visualization using React and D3. A single black circle tracks the user's cursor as it moves across an SVG canvas, updating its position in real time. The application uses React's `useState` and `useCallback` hooks to manage the mouse coordinates, while the `onMouseMove` event handler captures the clientX and clientY values. D3 v5 is loaded but only used for its `arc` import, which is not actually called in the visible code. The SVG rendering approach is handled entirely through React's JSX syntax.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
