{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A black circle follows the mouse cursor across a full-screen SVG, updating its position in real time as the cursor moves. The example uses React's `useState` and `useCallback` hooks to track the cursor's `clientX` and `clientY` coordinates, which are then passed as `cx` and `cy` attributes to the SVG `<circle>` element. The circle renders dynamically within an SVG canvas sized to the browser window, with ReactDOM mounting the component to manage updates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/80e78129e59f46979683c7c8910d8561?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
