{"version":"1.0","type":"rich","title":"Fork of Smiley Face Part II","description":"A single yellow circle follows the mouse cursor across a full-window SVG canvas. The React app tracks pointer coordinates through an `onMouseMove` event handler, updating the circle's `cx` and `cy` attributes via the `useState` hook. The rendering relies on ReactDOM and React 16.9.0, with `useCallback` to manage the event listener. Only one circle is displayed; the smiley face features from the source are commented out, leaving the interactive tracking visualization as the sole output.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/58979c24bc964058b62f09272e9c6e8b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
