{"version":"1.0","type":"rich","title":"Mouse follower","description":"A circle follows the mouse cursor across an SVG canvas, updating its position in real time. The example demonstrates React state management with a `useState` hook and the `onMouseMove` event handler, which captures the cursor's client coordinates and passes them to the circle's `cx` and `cy` attributes. React re-renders the SVG element on each mouse movement, while D3's `arc` import is present but unused, and no external data source is involved.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
