{"version":"1.0","type":"rich","title":"Smiley Face Part I","description":"This example renders a yellow smiley face using React and D3’s `arc` generator. The face consists of a large yellow circle with a black stroke, two black eye circles, and a mouth drawn as an arc path via `d3.arc()` with specified inner and outer radii and start/end angles. The SVG output is 960×500 pixels, and all shapes are positioned relative to a centered translation. The code uses React 17, D3 v7, and SVG rendering with hardcoded dimensions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ff9662503893465aa8ca55d286abb256?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
