{"version":"1.0","type":"rich","title":"Smiley face part IV","description":"A grid of eighteen smiley faces, each with randomized facial features, fills the viewport. The example demonstrates React component composition by assembling faces from separate `BackgroundCircle`, `Eyes`, and `Mouth` components, with `d3.arc()` generating the mouth path. Each face is an SVG rendered via React, with random values for stroke width, eye offset, and eye radius creating individual variation across the grid.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7cde17f75c5341e3a0ce76e5c0674aea?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
