{"version":"1.0","type":"rich","title":"Fork of Smiley Face Part II","description":"A single yellow circle follows the cursor across a full-window SVG canvas, its position driven by mouse movement events. The React component tracks pointer coordinates in state and re-renders the circle at the current location. The code uses React’s `useState` and `useCallback`, renders via `ReactDOM`, and updates an SVG circle element. The example demonstrates interactive mouse tracking in a React 16.9 environment.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4b2d99f2ee574ab6880b416b98452576?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
