{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A yellow smiley face with black circular eyes, rectangular eyebrows, and an arc-based mouth is rendered entirely in SVG. The example demonstrates fundamental DOM manipulation and animation with D3 v5, using `d3.select`, `d3.append`, and `d3.arc` to generate the facial features. Eyebrows animate via chained `transition` calls that move their group vertically over two seconds, then return. The face is centered using an SVG `<g>` element with a computed translation, and all geometric values are defined as named constants for clarity.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c67dc08b72824e4993b46d6eac99597b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
