{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A single SVG circle follows the mouse cursor across a 960 by 500 viewport. The React component uses the `useState` and `useCallback` hooks to track pointer coordinates from the `onMouseMove` event, updating the circle’s `cx` and `cy` attributes with each move. The circle renders with a fixed radius but no fill color, appearing as a black outline on a white background. D3 is loaded but not used in the rendering logic.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a08352c7deaa4d5191fbafdeece5d295?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
