{"version":"1.0","type":"rich","title":"Mouse Follower","description":"An interactive React and SVG visualization demonstrates mouse tracking by rendering a single black circle that follows the cursor across a 960x500 coordinate space. The app uses the `useState` hook to store the mouse position and a `useCallback`-wrapped event handler to update that state on every SVG `onMouseMove` event. The circle’s center coordinates are bound directly to the current mouse position, producing a seamless, real-time response. The initial position is set to the viewport’s center, and the circle radius is fixed at 30 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/567e93f8538b4b998910101e9cbeb699?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
