{"version":"1.0","type":"rich","title":"Mouse Tracking","description":"A single black circle tracks the user's mouse cursor across a blank SVG canvas. The visualization demonstrates how React state updates on every mouse movement event, with the circle's center position re-rendered accordingly. It uses React's `useState` and `useCallback` hooks along with the `onMouseMove` event handler, while D3 v5 is loaded but not directly used in the interaction logic.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0e61b34ca03d4f53bac3ab691b8fdec9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
