{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A single red circle follows the cursor across the entire browser viewport. The circle is rendered as an SVG `<circle>` element, with its center coordinates updated on every mouse move event. Built with React (using `useState` and `useCallback`) and rendered with `ReactDOM.render`, the application listens for `onMouseMove` on a full-window SVG and sets the circle’s `cx` and `cy` properties to the event’s client coordinates. The viewport dimensions are taken from `window.innerWidth` and `window.innerHeight`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/169aaec0100c4f4cb8777f49c982e81c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
