{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example builds a smiling face from basic SVG shapes using D3.js, with animated eyebrows that move up and down in a looping transition. The code selects an SVG element, centers a group, and appends a circle for the head, circles for eyes, rects for eyebrows, and a path for the mouth generated with the `d3.arc()` helper. Using `d3.transition()` and `.duration(2000)`, the eyebrows shift vertically twice, creating a repetitive motion. The demonstration focuses on fundamental DOM manipulation—such as `.append()`, `.attr()`, and chained transitions—while rendering entirely in SVG with no external data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/292df4cfc466454f901e2425edcd9757?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
