{"version":"1.0","type":"rich","title":"mouse follower","description":"A smiley face drawn with SVG circles follows the mouse cursor across the full browser window. The example uses React’s `useState` and `useCallback` hooks to track mouse position on the `<svg>` element, updating the circle’s `cx` and `cy` attributes in response to `onMouseMove` events. Rendering is handled by ReactDOM, with the viewport dimensions determined by `window.innerWidth` and `window.innerHeight`. The code includes a static yellow smiley face in a commented block, but the active visualization shows only a single black circle.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5b18f39324044fe2a80fee9eac8553dc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
