{"version":"1.0","type":"rich","title":"mouse follower","description":"A yellow smiley face follows the mouse cursor across an SVG canvas. The face’s components—eyes, brows, and an arc-shaped mouth—are built with React state and D3’s `arc` generator, repositioned via a `transform` attribute on each mouse move. The example uses `useState` and `useCallback` to track cursor coordinates, and ReactDOM renders the interactive graphic.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1b2914298e4f4f23bdcc42f1dfdf483b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
