{"version":"1.0","type":"rich","title":"Smiley","description":"A yellow smiley face is rendered as an SVG using React and D3. The face consists of a yellow circle with a black stroke, two black eye circles, and a mouth drawn as an arc path using the `d3.arc` API with specified inner and outer radii and angles. React manages the SVG elements, while D3’s `arc()` generator computes the mouth’s path data. The layout uses fixed pixel dimensions and positions centered on a 960 by 500 canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dc458bdd1bb7461dbf08ef0077759464?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
