{"version":"1.0","type":"rich","title":"Fork of Smiley Face Part II","description":"This example shows a single unfilled circle that follows the mouse cursor across the full browser window, rendered as an SVG element. The circle’s center coordinates update continuously on mouse movement, using React’s `useState` and `useCallback` hooks to manage and optimize state changes. The visualization is built with React 16.9 and ReactDOM, rendering directly to the DOM, with the SVG’s `onMouseMove` event driving the interactive behavior. The underlying code includes commented-out static smiley-face circles, indicating the fork’s evolution from a fixed illustration to a mouse-tracking interactive graphic.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5c1b4dadfa87428681ea372b177059ce?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
