{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example uses D3.js v5 to construct a smiling face from SVG primitives, with animated eyebrows that move up and down over time. The face consists of a yellow circle, two eyes, eyebrows, and a mouth drawn using an arc path. The animation is handled through chained `transition().duration(2000)` calls that alternately shift the eyebrow group’s `transform` attribute, creating a simple looping motion. The code relies on methods like `select`, `append`, and `attr` for DOM manipulation, along with D3’s `arc` generator for the mouth shape.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6beb3e78ba554c968d2e375c6827b2c2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
