{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A single black circle follows the mouse cursor across a blank SVG canvas. The React component tracks pointer coordinates via the `onMouseMove` event, updating the circle’s `cx` and `cy` attributes with the client’s position. Using `useState` to hold the origin and `useCallback` for the handler, it re-renders the circle at the new location on every movement. The example demonstrates dynamic SVG updates driven by React state changes without external data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/293aec1264564dc5a84414911d4437d9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
