{"version":"1.0","type":"rich","title":"Smiley Face Part 4","description":"This gallery example displays a classic smiley face composed of a yellow circular head with black outlines, two small eye circles, and a curved mouth arc. Built with React and D3 v7, it renders to an SVG canvas using D3’s `arc` generator to define the mouth’s inner radius, width, and start and end angles. The head is a separate React component, and all elements are positioned relative to the center using SVG group transforms.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/daffc2b916ca43e99d960d7e113016e9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
