{"version":"1.0","type":"rich","title":"Let's make a face with D3.js","description":"This example uses D3.js v5 to construct a smiling face from basic SVG shapes. A yellow circle forms the head, while two smaller circles become the eyes. The code animates the eyebrows using chained `transition().duration()` calls, moving them up and then back down over two seconds. A mouth is drawn using the `arc()` generator from D3’s shape utilities, creating a curved path. All elements are positioned relative to the SVG center using a `g` transform, and the entire composition is rendered as static SVG with animated attributes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e25727b105204ee2a89a0c59e50e5d72?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
