{"version":"1.0","type":"rich","title":"Let's make a Face with D3.js","description":"A smiling face rendered in SVG with D3.js animates its eyebrows in a repeating up-and-down motion. The code builds the face from basic shapes: a yellow circle for the head, two black circles for eyes, and an arc path for the mouth, all positioned within a centered group. D3 transitions, using `transition.duration` and chained `.attr` calls, move the eyebrow rectangles between two vertical positions over two-second intervals, creating a winking-like effect. The example uses D3 v5 selectors, the `arc` generator, and SVG attributes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e4ab619a24bd4ab499fa1d3050d45bd2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
