{"version":"1.0","type":"rich","title":"Fork of Smiley Face Part II","description":"This example builds an interactive smiley face using React and D3 v5. The page loads a CSS named color dataset from a GitHub gist and displays its file size, row count, and column count in a text overlay. A single circle follows the mouse position across the full window, rendering via SVG elements managed through React state and event handlers. The visualization demonstrates React’s `useState` and `useCallback` hooks for responsive, real-time updates, with D3’s `csv` method fetching and parsing the external data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0c25a25ef2824bdfa6f8fd400d81a555?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
