{"version":"1.0","type":"rich","title":"Circle Follower","description":"A circle follows the mouse cursor across an SVG canvas, updating its position in real time as the pointer moves. Built with React and d3.v7, the app uses React’s `useState` and `useCallback` hooks to track and update the mouse coordinates on every `onMouseMove` event, rendering a single `` element with a radius of 30 pixels. The example relies on SVG rendering within a 960×500 viewport, with the initial circle centered at the midpoint of the canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
