{"version":"1.0","type":"rich","title":"Smiley Face","description":"The example displays a grid of 18 cartoon smiley faces, each rendered as a yellow SVG circle with black eyes and a curved mouth. It shows how React components compose reusable SVG elements, where each face is generated from randomized eye radii. The code uses React 18 and D3 v7, specifically the `d3.arc` API to construct the mouth path, with an SVG linear gradient applied to the face backgrounds.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/17fc5b5db1d041ad9f670340121f3f34?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
