{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A D3.js smiley face is drawn with SVG shapes: a yellow circle for the head, two circles for eyes, rectangles for eyebrows, and a curved path for a mouth. The face is centered on an SVG canvas, and animated eyebrows and mouth move through a sequence of positions using D3 transitions with a two-second duration. The code explicitly uses D3's `select`, `append`, `attr`, and `transition` methods to manipulate DOM elements, building the face from primitive shapes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f347e79a05fd4fe689ac999834b51751?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
