{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A single circle tracks the mouse as it moves across a full-screen SVG canvas, with its position updating in real time to mirror the cursor’s coordinates. Built with React and ReactDOM, the app uses the `useState` hook to store the mouse position and the `useCallback` hook to handle the `onMouseMove` event on the SVG element. The viewport dimensions come from `window.innerWidth` and `window.innerHeight`, and the circle is rendered as an SVG `<circle>` element with a fixed radius of 30 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/439d5ab41b3948cf898b1168b28c4336?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
