{"version":"1.0","type":"rich","title":"HTML Starter","description":"This example draws a smiley face using D3 selections and SVG shapes. A yellow circle serves as the face, with black circles for eyes, rectangles for eyebrows, and a D3 arc path for the mouth. The eyebrows animate vertically through a chain of `transition().duration()` calls, moving up and down repeatedly. The code constructs the SVG elements by appending groups and shapes to the root `svg` element, using D3's `select` and `arc` functions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/29cbd2af588741e0aa8ead239744453d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
