{"version":"1.0","type":"rich","title":"Smiley Face Part 4","description":"The visualization renders a grid of eighteen procedurally generated smiley faces, each composed of SVG circles and an arc-based mouth. Built with React and D3 v7, the code imports the `arc` API from D3 to construct the mouth path, while `range` generates the array of faces. Each face randomizes its eye radius, eye offset, and mouth dimensions, producing varied expressions. The `Face` component composes smaller reusable components—`BackgroundCircle`, `Eyes`, and `Mouth`—within an SVG container, demonstrating modular React component design.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2b09cdd4304a4720b6298cf131657ee4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
