{"version":"1.0","type":"rich","title":"Smiley Face Part 1","description":"A grid of randomized smiley faces is rendered as SVG in React. Each face uses a yellow circle with a black stroke, two eyes, and an arc-based mouth. The `d3.arc` API generates the mouth path, while `d3.range` creates 18 face instances with randomly varied dimensions for eyes, stroke width, and mouth radius. The `FaceContainer` component translates the coordinate system to center each face within its 160 by 160 pixel viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/54ef0816a54c4af8b1ddbc447eec7127?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
