{"version":"1.0","type":"rich","title":"MouseFollower","description":"A circle follows the mouse cursor across an SVG canvas in real time. The React component tracks pointer coordinates through the SVG `onMouseMove` event handler, updating the circle’s `cx` and `cy` attributes. Using React hooks like `useState` and `useCallback`, the app re-renders only on cursor movement, while D3 v5 is loaded but unused in this minimal interaction. The initial mouse position is centered at (480, 250) within a 960 by 500 viewport, with the circle’s radius set to 30 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2a79182b647c472b94de42d63e1bfd79?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
