{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example demonstrates fundamental D3.js DOM manipulation by building a smiling face from SVG primitives—a yellow circle, two eyes, rectangular eyebrows, and an arc-shaped mouth—centered within an SVG. The code constructs the face using `select` and `append`, then animates the eyebrows upward and back down with chained `transition().duration(2000)` calls. It imports the `arc` helper from D3 v5 to generate the mouth path, and uses static attributes for sizing and positioning. The animation runs once on page load, showing a face whose eyebrows move without user interaction.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5b7e9368935d4d8cba51f33472f62dd7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
