{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A D3.js smiley face demonstrates fundamental DOM manipulation and animation. The code builds an SVG face from primitive shapes—a yellow circle for the head, eyes, a mouth via `d3.arc`, and rectangular eyebrows—centered using a translation. It then animates the brows upward and back over two seconds using chained `.transition().duration(2000)` calls, showing how to select elements, append shapes, and apply sequential transitions. The example uses D3 v5 and renders entirely in the browser as an animated SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2e4450631e464ad483acaaeb49551cef?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
