{"version":"1.0","type":"rich","title":"Mouse follower","description":"A smiley face rendered as an SVG circle follows the mouse cursor across the browser viewport. The React application tracks pointer movement via an `onMouseMove` handler, updating the circle's `cx` and `cy` coordinates with the cursor's client position. The visualization uses React's `useState` and `useCallback` hooks to manage state, and D3.js is loaded for potential data manipulation, though the current implementation relies solely on SVG primitives within a React component.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
