{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A black circle follows the mouse cursor across a blank SVG canvas. The example demonstrates React state management with the `useState` and `useCallback` hooks, updating circle coordinates via the `onMouseMove` event. It renders a single `<circle>` element using ReactDOM, with a fixed radius of 30 pixels, and initializes the pointer position at the center of the 960×500 viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a07ffc7c37bd43178f18bf9f8b85255e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
