{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A single black circle follows the mouse as it moves across an SVG canvas. The React component tracks pointer coordinates through an `onMouseMove` event handler and updates the circle’s `cx` and `cy` attributes via React state. The example imports the `arc` function from d3 but does not use it, relying instead on plain SVG rendering and React’s `useState` and `useCallback` hooks for interactivity.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
