{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"D3.js constructs an animated smiley face by manipulating SVG shapes. A yellow circle forms the head, with two static eyes and a mouth drawn using the `arc` path generator. The eyebrows, rendered as rectangles, animate upward and downward over two seconds using chained `transition().duration()` calls on the SVG group, demonstrating fundamental DOM selection and attribute mutation. The code uses the `select` API to target the root SVG element.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bfde7d18040141d68a86ea4d35632a5e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
