{"version":"1.0","type":"rich","title":"mouse_follower","description":"A yellow circle follows the mouse cursor across a blank SVG canvas, updating its position in real time as the user moves the pointer. The visualization uses React state with the `useState` and `useCallback` hooks to track mouse coordinates, and ReactDOM renders the circle via SVG. D3 v6’s `arc` function is imported but unused; the core interaction relies on the SVG `onMouseMove` event handler. The fixed canvas is 960 by 500 pixels, with the circle’s radius set to 30.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ba64ae108c6d4f48ad7b2a95b9d0f2ba?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
