{"version":"1.0","type":"rich","title":"Mouse follower","description":"A yellow circle follows the mouse cursor across an SVG canvas, with its position updating in real time as the pointer moves. The React component uses the `useState` and `useCallback` hooks to track mouse coordinates via an `onMouseMove` event handler, rendering the circle with dynamic `cx` and `cy` attributes. Built with React 17 and D3 v7, the example demonstrates a simple interactive data-binding pattern without external data sources.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
