{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A full-screen SVG circle follows the mouse cursor across a blank canvas. The React component tracks pointer coordinates via an `onMouseMove` event listener, updating component state through `useState` and `useCallback`. The circle's center position (`cx`, `cy`) is derived from the state's `x` and `y` values, rendering with D3.js v6. The canvas resizes to the window dimensions, and the circle has a fixed radius of 30 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/771c609c3c8b4fd9ab69c1b3710cff7a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
