{"version":"1.0","type":"rich","title":"Fork of Smiley Face Part II","description":"This example shows a smiley face whose single eye follows the mouse cursor across the screen, with the circle’s position updating in real time. Built with React, it uses the `useState` and `useCallback` hooks to track mouse coordinates and re-render an SVG `<circle>` element. The SVG’s `onMouseMove` event handler triggers state updates, and ReactDOM renders the component into the root div. The visualization uses a fixed viewport matching the browser window and demonstrates interactive pointer tracking in a minimal, responsive setup.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7d34ddf4fd214bd5beff703d83aa808f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
