{"version":"1.0","type":"rich","title":"Smiley Face Part I","description":"A yellow circle with a black outline and a black arc smile follows the mouse cursor across an SVG canvas. Built with React and D3 v7, the smile is generated using the `arc()` generator from D3, while React's `useState` and `useCallback` hook react to `onMouseMove` events. The circle renders as an SVG element at the cursor's current position.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c3354ca50a7c467397bbf6a9cff1b996?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
