{"version":"1.0","type":"rich","title":"Smiley face part 1","description":"This example renders a static smiley face in an SVG using React and D3. The face is centered in a 960×500 viewport, with a yellow background circle, black stroke, two eye circles, and a mouth drawn as an arc path. The code defines a `BackgroundCircle` React component and uses the `arc()` generator from d3 to create the mouth’s path geometry. All shapes are positioned via a group transform, while constants like `eyeOffsetX`, `eyeRadius`, and `mouthRadius` control the facial feature placement.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/53f6a7a0037a43beaee14c00f6cfdd45?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
