{"version":"1.0","type":"rich","title":"Hello HTML","description":"This example renders a grid of smiley faces using React components and D3’s arc generator. Each face consists of a yellow background circle, two black eyes, and a mouth drawn with `d3.arc()`, all composed inside an SVG via a shared `FaceContainer` that applies a translation transform. Fifty faces are generated with randomly varying eye radii, producing subtle visual differences. The code demonstrates component reuse, D3’s `arc` API for path generation, and React’s rendering of SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/af78cbc9c8084615b97cf0cd27501bcc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
