{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A smiley face follows the mouse cursor across an SVG canvas, its position updating in real time with every pointer movement. The example combines React 16.9's `useState` and `useCallback` hooks to manage the circle's `cx` and `cy` attributes, while D3 v5 supplies the `arc` import. Rendering is handled through ReactDOM's `render` method, which places an interactive `<svg>` with an `onMouseMove` listener into the page root.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5149169b6fc14ef6956a3a3bca3529db?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
