{"version":"1.0","type":"rich","title":"Fork of Let's make a face with D3.js!","description":"This example uses D3.js to construct an animated smiley face from basic SVG shapes—a yellow circle for the head, separate circles for the eyes, rectangles for eyebrows, and a curved arc for the mouth. The eyes and mouth are static, while the eyebrows perform a looping transition that moves them up and down over two seconds each way. The code demonstrates fundamental DOM manipulation with `d3.select` and `d3.append`, and uses `d3.arc` to generate the mouth’s path, with `transition().duration()` controlling the animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6630b029369148fb9f829402c530be37?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
