{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A React-based SVG visualization tracks the mouse cursor with a single orange circle, updating its position in real time as the user moves across the viewport. The app uses React’s `useState` and `useCallback` hooks to manage the cursor coordinates, while D3’s `arc` import is included but unused. The circle renders via SVG inside a fixed 960×500 canvas, with the initial position centered before any mouse movement. The `onMouseMove` event handler on the `<svg>` element captures client coordinates and triggers a state update, seamlessly animating the follower through React’s rendering lifecycle.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/57e616081d034f77af576a7c902a1049?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
