{"version":"1.0","type":"rich","title":"Fork of Let's make a face with D3.js!","description":"A D3.js smiley face demonstrates declarative SVG manipulation with animated eyebrow movement. It constructs the face from basic shapes—yellow circle, eye circles, eyebrow rectangles, and an arc-generated mouth—positioned with transforms. The code uses `d3.select`, `attr`, and `append` to build the DOM, then chains `transition().duration(2000)` twice to raise and lower the eyebrows. The `arc` generator draws the mouth with specified inner/outer radii and angles, all rendered as static SVG geometry in a 960x500 viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7ca5caebadd7497e909a33ba9cd60d14?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
