{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiley face built with D3.js demonstrates basic DOM manipulation. The SVG face has blue circular head, green eyes, and an arc-based mouth, with rectangular eyebrows that animate up and down using chained `transition` calls. The code uses d3.select to target the SVG, d3.arc to generate the mouth path, and attribute methods like `.attr` to position elements. Eyebrow movement is achieved through sequential `.transition().duration()` operations that translate the eyebrow group vertically.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b17a52bd9b7244878311ac9780abea09?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
