{"version":"1.0","type":"rich","title":"Smiley Face Part I","description":"This example renders a yellow smiley face in SVG using React and D3 v7. It shows a circular face with two eyes and a semicircular mouth, all positioned relative to a central coordinate system via a group transformation. The code uses `d3.arc` to generate the mouth path, with explicit `innerRadius` and `outerRadius` values, while the face and eyes are simple SVG `circle` elements. Stroke width and radius calculations adjust the face size based on the fixed 960×500 viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9ad8aeaac81845f2b1531ad5ae476691?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
