{"version":"1.0","type":"rich","title":"8.00 Mouse Follower","description":"A single dark circle moves within an SVG viewport in direct response to the mouse cursor. The example demonstrates a simple React state update mechanism: the `onMouseMove` event on the `<svg>` element captures cursor coordinates, which are stored in `mousePosition` via `React.useState` and applied to the circle’s `cx` and `cy` attributes. The initial position is centered at (480, 250), and the circle’s radius is set to 10% of the viewport height. Crafted with React 17 and ReactDOM, it renders a pure SVG without external data or animation libraries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c1ff78435125492196c82ca083314086?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
