{"version":"1.0","type":"rich","title":"Fork of Smiley face","description":"A yellow smiley face is drawn on an SVG canvas, centered and sized to the viewport. The graphic shows a static face with two black eyes, eyebrows, and a curved mouth, while the eyes transition from their initial state to black over three seconds after a one-second delay. The code uses D3 v6 selections and transitions, including `transition.delay()` and `transition.duration()`, to animate the eye fill colors. The face is constructed with SVG circle, rect, and path elements, using `d3.arc()` for the mouth’s curved shape, all within a centered group.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/57da4d7a9c79492c9cda7f1ac4b290b4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
