{"version":"1.0","type":"rich","title":"Mouse follower","description":"A circle follows the mouse cursor in real time across an SVG canvas, highlighting the immediate connection between pointer movement and visual feedback. The visualization uses React state management, with a `useState` hook tracking the cursor's `clientX` and `clientY` coordinates, which are updated via a callback on the SVG's `onMouseMove` event. Rendered with React’s `ReactDOM.render`, the circle’s position transitions smoothly as the state changes, while D3.js is loaded but not actively used in the logic. The example demonstrates a simple, responsive interaction pattern.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
