{"version":"1.0","type":"rich","title":"Mouse Follower","description":"An interactive SVG circle follows the mouse cursor across a 960x500 canvas. The React application tracks pointer movement via the `onMouseMove` event handler, updating the circle's center coordinates with each `clientX` and `clientY` value. Using `useState` for position state and `useCallback` to optimize the event handler, the code renders a single red circle (radius 30) whose position updates in real time. The example demonstrates a basic React-D3 integration, with the visualization rendered entirely through React's declarative SVG output.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b135e5f26ed148989c8849ace9c6739c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
