{"version":"1.0","type":"rich","title":"Smiley Beginner D3","description":"This example displays a simple smiley face composed of SVG shapes: a yellow circle for the head, two small circles for eyes, and a curved arc for the mouth. Built with React and D3 v7, it uses the `arc()` generator to define the mouth’s path with specified inner and outer radii and angles. The head and eyes are drawn with React’s `<circle>` elements, while coordinates are calculated relative to the center of the 960×500 viewport. Rendering occurs via ReactDOM, with D3 loaded alongside React.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3c9e313bcac848ae944fa99391446071?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
