{"version":"1.0","type":"rich","title":"Smiley Face","description":"A yellow smiley face is drawn with SVG using D3.js and React. The face includes a circle for the head, two eyes, and an arc-based mouth created with the `d3.arc` API. The eyebrows are animated vertically using D3 transitions, moving up and down over 1.5-second intervals. The code uses D3 selections to append and transform SVG elements, with all positions calculated from the SVG’s width and height attributes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1e840fd07a4e46428ab6a5eccd39d0b3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
