{"version":"1.0","type":"rich","title":"Smiley Face","description":"A smiling face rendered as a yellow circle with black eyes and a curved mouth, built using React and D3.js. The face is drawn entirely with SVG shapes: two `<circle>` elements for the eyes, a large `<circle>` for the head, and a `<path>` created by the `d3.arc()` generator with a constant inner and outer radius to form the mouth. The `arc()` API sets start and end angles to create a full ring, while stroke widths and coordinates position each element relative to the center of a 960×500 viewport. No external data is loaded; all geometry is hard-coded.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f159647393e14c83b90d60f340e81a85?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
