{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiley face drawn with D3.js shows its eyebrows moving up and down in a looping animation. The code builds the face using SVG shapes: a yellow circle for the head, two circles for eyes, rectangles for eyebrows, and a path generated with the `d3.arc` function for the mouth. Eyebrow motion is created with chained `transition` and `duration` calls that alternate between two vertical positions. The example demonstrates fundamental DOM manipulation and data-driven styling using D3 v5’s selection, arc, and transition APIs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9c6c5a7d203e49c382abe78dddce79f4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
