{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A plain SVG circle follows the user's mouse cursor across a 960-by-500 canvas. The React component tracks `clientX` and `clientY` from a `mousemove` event handler, updating state to reposition the circle's `cx` and `cy` attributes. The example uses React's `useState` and `useCallback` hooks, with D3 v7 loaded for potential supplementary utilities, though rendering relies solely on SVG elements and React's declarative updates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2477d35c957547dea1f1eb67ae9f0e2d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
