{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A circle follows the mouse cursor across an SVG canvas in this React-based visualization. The example uses React's `useState` and `useCallback` hooks to track `clientX` and `clientY` coordinates from a mouse move event, updating the circle's `cx` and `cy` attributes in real time. Rendered with D3 v6 for SVG elements and React 17, the circle starts centered at (480, 250) with a radius of 30 pixels. No data source is involved; the visualization demonstrates interactive event handling and state-driven positioning.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
