{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiley face is drawn with SVG shapes, including a yellow circle head, black eyes, and an arc-based mouth. The example demonstrates fundamental D3.js DOM manipulation by selecting the SVG element, appending a group, and building each facial feature with `select`, `append`, and attribute setters. The left eyebrow is a rectangle that animates up and down using chained `transition().duration()` calls with 2000-millisecond delays. The mouth is generated with the `d3.arc` shape generator, using specified inner and outer radii and angular ranges.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4977d18f633b4b0b9f2f93aaec734bfa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
