{"version":"1.0","type":"rich","title":"Mouse mover","description":"A circle follows the mouse cursor as it moves across an SVG canvas. The React component tracks pointer coordinates via an SVG `onMouseMove` event handler, updating the circle’s `cx` and `cy` attributes through state. D3’s `arc` import is unused here; rendering relies on React’s `useState` and `useCallback` hooks with a plain `<circle>` element. The visualization demonstrates real-time event-driven SVG updates in a React-D3 hybrid setup.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8a0785c29ee14b17b4ad0ccc1c86d91a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
