{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example builds a smiling face out of SVG shapes—a yellow circle, two eyes, eyebrows, and an arc mouth—anchored at the center of a 960-by-500 viewport. Using d3.select and append, it constructs a group hierarchy for the eyes and eyebrows, then applies a repeating transition to the eyebrow group, shifting its transform up and down over two-second intervals with d3’s transition().duration. The mouth is drawn via d3.arc with inner and outer radii, while the face’s static elements remain fixed.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/827f8d5ae85b43a29a1bb602c20a5c7e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
