{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A circle follows the mouse cursor across an SVG canvas. The example demonstrates a basic interactive pattern using React’s `useState` and `useCallback` hooks to track pointer coordinates and update the circle’s position. The D3.js library supplies the SVG rendering, while React manages state and event handling through `onMouseMove`. The initial mouse position is centered on the canvas, and the circle has a fixed radius of 20 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
