{"version":"1.0","type":"rich","title":"Smiley Face","description":"A grid of randomized smiley faces appears, each rendered as a yellow circle with black outline, two eyes, and an arc-shaped mouth. The faces are generated using React components that compose SVG elements, with D3’s `arc` function calculating the mouth path. Random values for stroke width, eye offset, eye radius, and mouth dimensions create variation across the 18-face layout. The example demonstrates reusable React components and D3 integration for declarative SVG generation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d674355be75f4c9391ed1629008ea3ac?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
