{"version":"1.0","type":"rich","title":"Smiley Face Part I","description":"A grid of twenty simple smiley faces, each rendered as an SVG circle with white-outlined eyes and a curved mouth. The example demonstrates reusable React components for the face, background, eyes, and mouth, composed within a container that centers each face. Random values for eye radius, mouth width, and mouth radius make every face slightly different. The code uses D3 v7’s `arc` generator to draw the mouth path, while React manages the component hierarchy and rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4ccfc8a6cc4b49beba209e37a5535e11?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
