{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A yellow circle tracks the user's mouse cursor across an SVG canvas, updating its position in real time. The React app listens for mouse-move events through an SVG `onMouseMove` handler, storing coordinates in state. D3.js renders the circle, while React's `useState` and `useCallback` manage the dynamic positioning.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/48daf59ae17c451abe892c46e0eb876a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
