{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A D3.js visualization assembles a smiley face from SVG shapes, including a yellow circle, two eyes, rectangular eyebrows, and an arc-shaped mouth. The code demonstrates fundamental DOM manipulation by building each facial feature through chained `attr` and `append` calls. Using `d3.select`, `d3.transition`, and the `d3.arc` path generator, the eyebrows animate over four seconds, alternately shifting downward and returning, while the static features remain unchanged. The SVG canvas is 960 by 500 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a82b034716cc460a87186ee7ee18ff03?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
