{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A smiley face follows the mouse cursor across a full-screen SVG canvas. The React component tracks pointer coordinates via the `onMouseMove` event and stores them in state with the `useState` hook, updating the circle's `cx` and `cy` attributes through re-rendering. The `useCallback` hook memoizes the event handler, while rendering relies on React DOM and plain SVG elements with no external charting library.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6b81dc92099545bcadd898b008183953?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
