{"version":"1.0","type":"rich","title":"Fork of Mouse follower","description":"A smiley face made of a single circle follows the mouse cursor across a full-window SVG canvas. The React app tracks pointer movement through an `onMouseMove` event handler, storing the cursor’s client coordinates in state and re-rendering the circle’s `cx` and `cy` attributes based on that position. The code uses React 16.9’s `useState` and `useCallback` hooks, with D3 v7 loaded for potential visualization utilities, though the rendering itself is plain SVG without D3-specific data joins or scales.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/38f4c0cc8e6d4e448ffbe90dbaa0df32?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
