{"version":"1.0","type":"rich","title":"Let's make a face with D3.js","description":"This example builds a stylized smiling face from basic SVG shapes using D3.js v5. It draws a yellow head circle, two eyes, and a mouth path created with the `d3.arc` generator. The animation uses chained `transition().duration()`.attr calls to make the eyebrows move up and down, creating a simple facial expression. The code demonstrates SVG rendering with D3’s selection and attribute manipulation APIs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
