{"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 out of SVG shapes, with animated eyebrows that move up and down. A yellow circle forms the head, two circles serve as eyes, rectangles become eyebrows, and a path generated with the `d3.arc` helper creates the mouth. Using a `transition().duration(2000)` chain, the eyebrow group toggles its vertical translation, shifting it downward then returning it to the original position. The code explicitly binds SVG elements via `select` and `append`, relying on D3 v5’s modular imports for `select` and `arc`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0f13589d322d4070b220b84115e4e5ea?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
