{"version":"1.0","type":"rich","title":"Smiley face part1","description":"A grid of twenty smiling faces, each rendered as a red SVG circle with a black stroke, black eyes, and a mouth arc, demonstrates a reusable component-based approach to data visualization. Built with React and D3, the code constructs each face from modular React components that accept parameters for geometry and styling. The mouth uses D3’s `arc` API to generate a path, while the face positions are fixed, but eye radius is randomized. The example shows how to compose SVG primitives into structured, parameterized visual elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9f3ccfe6417440ea86999f9f4979f0db?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
