{"version":"1.0","type":"rich","title":"Fork of Smiley Face Part II","description":"A circle follows the mouse cursor across a full-screen SVG canvas. The example demonstrates a minimal React application that tracks pointer movement and updates the circle's position in real time. It uses React's `useState` and `useCallback` hooks to manage the mouse coordinates, which are captured via the SVG container's `onMouseMove` event. The circle is rendered as an SVG `<circle>` element with a fixed radius, and the app is mounted into the DOM with `ReactDOM.render`. The code imports React and ReactDOM from their production UMD builds.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c40351c9b8f042768b6a64927d6e52ef?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
