{"version":"1.0","type":"rich","title":"Smiley Face - E9","description":"A grid of randomly generated smiley faces demonstrates modular React component composition. Each face is defined recursively through separate files for the face container, background circle, eyes, and mouth, while the `index.js` file uses `d3.range` to map over an array and render 18 faces. The mouth uses `d3.arc` to create a semicircular path. All parts are rendered as SVG elements with randomized stroke widths, eye offsets, and radii, creating varied expressions within a uniform yellow and black style.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/edabd89c4dfc4fe8959537f6397fd98c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
