{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiling face rendered as SVG shapes in D3.js v5 shows animated eyebrow movements. The code builds the face using `d3.select`, `d3.append`, and `d3.arc` to create a yellow circle head, two eyes, and a mouth. Eyebrows are rectangles that move up and down via chained `transition().duration()` calls, each lasting two seconds. The example demonstrates fundamental DOM manipulation with D3's imperative API, drawing all elements on a 960×500 SVG canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dbe585e1dd904d659a237b1c770b8b14?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
