{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A yellow circle tracks the mouse cursor in real time within an SVG canvas, using React to manage the circle's position as state. The `App` component listens to `onMouseMove` events on the SVG element, updating the circle's `cx` and `cy` attributes via `useState` and `useCallback`. The example integrates React with D3 for SVG rendering, with the circle initially centered at 480,250.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2cfdd027d4a2489887be98b781a3de49?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
