{"version":"1.0","type":"rich","title":"Fork of Smiley Face Part II","description":"A single gray circle follows the user's mouse across a full-screen SVG canvas, updating its position in real time as the pointer moves. Built with React and ReactDOM, the application uses the `useState` and `useCallback` hooks to track the mouse's client coordinates via an SVG `onMouseMove` event handler. The circle's `cx` and `cy` attributes are bound to the tracked state, while the viewport dimensions are read directly from `window.innerWidth` and `window.innerHeight`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8dd5b84f552f4f19be4b1196344f9ee8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
