{"version":"1.0","type":"rich","title":"Smiley Face - homework","description":"A smiling face is drawn as a yellow circle with black outline, two black eyes, and a partial arc for a mouth, all rendered as SVG in React. The code uses `d3.arc` to compute the mouth path, with fixed dimensions for features. A green hat shape is added via two rotated rectangles. D3 and React are loaded from CDNs, and the visualization appears centered on a blank canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/56e032678ea44d258fe5ad57bde191cd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
